Fonts
Foreword
The bulk of Fedora software relies on OpenType compliance and was tested against compliant fonts.
Unfortunately, most font makers feel the OpenType specification is a document written by “software people” for “software people”. They spurn its recommendations. They can not be relied upon to release fonts in a software-friendly state, nor to fix the resulting problems, nor to provide useful advice.
To enable the packaging of fonts by non experts, Checklist provides a list of sanity rules. Most are short unambiguous one liners, easy to understand and apply. Do read this list, even if it feels long. Unless your upstream is a model of discipline, you WILL need it. Avoid Exceptions if you do not feel ambitious – here be dragons.
Once you sorted what to package using the checklist, the rpm-specific part of fonts packaging is simple:
-
take our spec templates,
-
fill in the blanks with descriptions and the file lists resulting from the sorting.
Fedora automation will do the rest.
Tooling provides in-depth documentation of those templates, and other operational tips. The operational tips are useful. The spec templates documentation, not so much. The templates are commented and will usually be self-explanatory.
Lastly, Rationale provides some help, in case a third party attempts to confuse you. A lot of upstreams are dead set against applying OpenType recommendations. They will provide elaborate argumentation, on why the common rule does not apply to them.
Checklist
Legal
-
Font files MUST comply with our licensing rules.
-
Trademark uses MUST be authorized by their owners,
-
trademarks may occur in font naming or font content (logos…).
-
-
Registered names or trademarks MUST NOT prevent downstream modifications,
-
requiring a rename on significant modification is acceptable.
-
Packaging unit: an ideal font family
Because fonts upstreams are, on average, extremely messy, a large part of packaging fonts involves sorting files and fixing font file metadata to produce the consistent and reliable font catalog expected by applications and users.
Font family
A font family is composed of font files, that share a single design, and differ ONLY in:
Those parameters correspond to the default axes of OpenType variable fonts. |
-
Packagers MUST apply the definition provided in this section to determine font family boundaries,
-
it takes precedence over application support concerns, over upstream and packager habits and practices.
-
See also the Fontconfig section.
Font file formats
OpenType: one standard, five formats
OpenType uses an SFNT container around bitmaps ( |
-
Other font formats MUST be converted to OpenType,
-
except for fonts, intended to be used in the console (NOT a terminal emulator): see Bitmap console fonts.
-
-
Font packages MUST NOT contain font files in non OpenType formats.
Font packages
A font package, is an installation (RPM) package, containing OpenType font files. It MAY be produced by a source (SRPM) package, that also produces other (font or non-font) packages. Other kinds of font packages are out of scope for this document. |
-
A font family MUST NOT be packaged in multiple or mixed OpenType formats,
-
except for variable font data,
-
except when mixing is required, to achieve full symbol (glyph) coverage,
-
except as an application workaround; see Packaging a font family in multiple OpenType formats; application support.
-
-
Both variable and non-variable OpenType font files, SHOULD be packaged, for a given font family.
-
OpenType format mixing SHOULD be justified in a comment within the
spec
file. -
OpenType collection formats SHOULD be avoided.
Fontconfig
-
Font packages SHOULD include the fontconfig files, that define the selection and substitution rules applying to their font files,
-
written by the packager if upstream does not provide them.
-
-
Fontconfig rules MUST rewrite
family
andstyle
when they are not compliant with OpenType WWS rules:-
family
MUST NOT contain Weight, Width or Slope attributes (ideal WWS family name, Name ID 21), -
style
MUST contain only Weight, Width or Slope attributes (ideal WWS subfamily name, Name ID 22), -
Name ID 21 & 22 fields may exist or not in the packaged font files, and may be correct or not. The packager MUST set the correct value at the fontconfig level if the value fontconfig extracts from font files is incorrect.
-
-
Fontconfig rules MUST rewrite
family
to remove format attributes when they exist,-
for example:
OT
,TT
,Variable
,Graphite
,G
, etc, -
except when Packaging a font family in multiple OpenType formats; application support; in that case the removal MUST only be done for the font package providing the default format.
-
-
Fontconfig rules MUST rewrite
family
to remove coverage attributes when they exist,-
for example:
Math
,Emoji
,Color Emoji
,Hebrew
,Arabic
,Thai
,LGC
, etc, -
except when several font files provide the same coverage, requiring a qualifier to distinguish between them; in that case the removal MUST be done for the default file, and other files MUST be treated as parts of separate font families.
-
-
Fontconfig rules MUST rewrite
fullname
to<family> <style>
if it has a different value,-
either natively or as a result of previous rewrites,
-
except for the default style, usually
Regular
, for whichfullname
=<family>
.
-
-
Fontconfig rules MUST rewrite
fontversion
when several font files provide the samefullname
and have overlapping coverage,-
either natively or as a result of previous rewrites,
-
fontconfig will merge the result, higher
fontversion
taking precedence over lower, -
therefore,
fontversion
MUST be set by the packager, to define the correct ordering.
-
-
Fontconfig rules SHOULD define the generic family, a font contributes to,
-
a single generic family: the packager MUST choose,
-
using the correct priority: lower takes precedence over higher.
-
-
Fontconfig rules SHOULD list what other font families, the provided font family can substitute for.
-
typically, anterior namings, known forks, alternatives with the same font metrics…
-
also, the reused fonts families when Assembling different-family font packages: partial designs.
-
-
Fontconfig rules SHOULD define the font families, that can be used to complete the font family,
-
in all cases: at least the generic family and the substitutes defined before,
-
generic family last in completion order.
-
-
Packagers SHOULD attempt upstreaming those fixes,
-
make the font naming correct in the upstream font files,
-
contribute the other fontconfig rules upstream, so they are distributed with the font files.
-
-
Packagers SHOULD consult the fontconfig maintainer and mailing list when in doubt,
-
to get guidance and identify real-world tricky cases that call for fontconfig evolutions.
-
See also the Tooling section for fontconfig syntax guidance.
Source (SRPM) package break-up
-
Separate source archives MUST be packaged in separate
spec
files,-
except when those contain parts of the same font family and upstream coordinates their release.
-
-
spec
files SHOULD track a single font family,-
except when distinct font families are only released upstream in a common archive.
-
-
Packagers SHOULD ask upstream to split unrelated font families in separate versioned source archives,
-
and package font families from their actual respective upstreams when they are bundled with other material in a third party project.
-
Installation (RPM) package break-up: font packages
-
Packagers MUST ship each font family in a single dedicated font package,
-
all the files that, after fontconfig fixing,
-
share the same
family
value:family
=<common family>
-
or differ only in optical sizing:
family
=<common family> <optical sizing attribute>
,
-
-
except when released as un-coordinated sources, that are easier to track in separate
spec
files, -
except for huge families, that consume a lot of storage space; huge font families MAY be broken up in coverage-specific font packages,
-
-
Font packages MUST limit themsemselves to OpenType font files and their associated fontconfig, appstream, legal and documentation files,
-
for reasonable non-bulky interpretations of documentation files.
-
See also the Tooling section.
Other upstream files
Support for other font systems, for specific applications, non-OpenType font formats, bulky documentation, TEX, CSS, or JSON files… MUST be split in separate non-font packages, that SHOULD install outside For compatibility reasons, OpenType font files MAY be exposed outside |
Building
-
Packagers SHOULD build font files from sources,
-
whenever their prefered modification format is not the packaged OpenType format
-
and if the required toolchain is available as free software under Linux
-
Dependencies in font packages
-
Font packages MAY require or supplement other font packages, when they contain the same font family,
-
as defined in Assembling same-family font packages.
-
-
Font packages SHOULD recommend other font packages, when they contain a reused font family,
-
as defined in Assembling different-family font packages: partial designs.
-
-
Font packages SHOULD suggest other font packages, when they contain a better version of the same font family,
-
better: more complete coverage, later enhanced fork, canonical version of the design…
-
-
Font packages MAY suggest or enhance font packages, containing other font families,
-
this should be used sparsely, to avoid imposing packager preferences on users.
-
-
Font packages SHOULD depend on the basic font support package set, defined in the font packaging templates and macros.
-
Except for the preceding, font packages MUST NOT depend, in any form, on any other package.
Dependencies to font packages in other packages
-
Non-font packages MAY suggest or recommend font packages,
-
the weakest
Suggests
form is preferred overRecommends
, except in presence of strong pre-existing user habits.
-
-
Non-font packages SHOULD use the
font()
namespace to depend on font packages. -
Non-font packages SHOULD NOT require specific font packages, and leave font selection to end-users,
-
except when the packaged software actually relies on those specific font packages,
-
except for convenience font metapackages, as defined in Assembling different-family font packages: font metapackages.
-
-
Non-font packages SHOULD require
font(:lang=en)
when they fail in the absence of system fonts,-
hardcoding specific font families is not future-proof.
-
-
Non-font packages MAY require font packages by name, when relying on specific on-disk font file paths,
-
ie when software is not
fontconfig
-aware, -
however, there is no obligation for font packagers to keep those paths stable between releases. Font file formats are flexible, making any on-disk file layout temporary. Converting applications to fontconfig use is best.
-
Assembling different-family font packages: partial designs
Font reuse and font extension
Because font creation is hard work, font designers will often publish partial new designs:
|
When packaging such a partial design:
-
The font package containing the new font family SHOULD recommend the package containing the original font family,
-
only the core package of the original font family in case of Assembling same-family font packages.
-
-
Re-use recommendations SHOULD use the
font()
namespace.
Assembling different-family font packages: font metapackages
-
Packagers MAY provide convenience font metapackages,
-
for example, when an upstream releases a collection of font families, intended to be used together,
-
a common case is matched serif, sans-serif and monospaced font families.
-
-
Font metapackages MUST NOT use the same naming conventions as actual font packages,
-
they MUST NOT be named
<something>-fonts
, -
they MAY be named
<something>-fonts-all
.
-
-
Font metapackages MUST require, recommend or suggest separate font packages, that conform to this document,
-
Font metapackages SHOULD use the
font()
namespace to require, recommend or suggest actual font packages, -
Font metapackages SHOULD NOT contain any other file, except for documentation.
Exceptions
Bitmap console fonts
-
Bitmap console fonts MAY be packaged in a legacy font format, understood by kbd.
-
Bitmap console fonts MUST be installed in
/lib/kbd/consolefonts/
not/usr/share/fonts
. -
Bitmap console font packages SHOULD be named
<something>-fonts-console
not<something>-fonts
.
Console fonts
As long as kbd and systemd-vconsole can not use the same file formats as the rest of the system, bitmap console fonts are effectively private kbd resources. They will be ignored in the rest of this document. It does not apply to them. |
Assembling same-family font packages
-
A font family MUST NOT be split over several font packages, unless one of the exceptions listed above applies.
When a font family is split over a set of several font packages:
-
Involved packagers MUST choose a core font package.
-
This core package SHOULD contain the font files, necessary to provide a minimal scope of the font family.
-
This core package MAY contain fontconfig rules, for all the font files composinng the font family,
-
fontconfig ignores rules that do not match installed files.
-
-
This core package MUST be named as if it contained the whole font family.
-
This core package MUST NOT require any other package in the set.
-
The other packages of the set MUST require, directly or indirectly, this core package.
-
The other packages of the set MUST supplement, directly or indirectly, this core package.
-
The other packages of the set MUST NOT use the
font()
namespace to require or supplement other parts of the set,-
Splitting a font family interacts badly with
font()
auto-provides.
-
-
All the packages involved in an indirect require or supplement chain MUST be part of the set.
Packaging a font family in multiple OpenType formats; application support
-
Packagers MUST make a reasonable effort, to get applications that do not support all OpenType formats, fixed upstream.
-
If that fails, as a last ressort, packagers MAY request a FESCo exemption, to package a limited number of font families in multiple OpenType formats.
-
Packagers MUST ensure that the resulting additional font data, is separated in distinct font packages,
-
that the average Fedora user can install those font families in a single format,
-
that he is not left wondering, which package to install.
-
Tooling
Creating font packages by hand can be extremely repetitive, error-prone and labor-intensive. Therefore, fonts packaging is heavily automated. It relies on numerous macros and variables to define what goes where.
Those macros and variables are defined in the fonts-rpm-macros
package. The fonts-rpm-templates
package contains spec
and fontconfig
templates, corresponding to common fonts packaging needs.
Fontconfig
The fonts-rpm-templates
package contains fontconfig
templates, corresponding to common fonts packaging needs.
Using fontconfig, you can help users and software make sense of broken font files.
On brokenness and interoperability
Fixing may imply behaviour differences, with entities that chose another mitigation strategy. The root cause of those differences is the upstream release of files in a broken state. Producing daring glyph shapes is the designer prerogative. That artistic license does not extend to flouting technical conventions, software relies on. Upstream should always be given the chance to fix its files. If it does not care about our needs, fixing downstream is second best. Inflicting intact breakage on our users is always worst. |
Some applications
-
The Foo project releases
Foo Narrow Oblique
. Because the font maker remembers early font formats only allowed 4-style family grouping (Name ID 1 and 2), it declares it asfamily: Foo Narrow
andstyle: Oblique
. The fontconfig rules forFoo Narrow Oblique
MUST rewrite it to the recommended WWS-compliantfamily: Foo
andstyle: Narrow Oblique
(Name ID 16/17 or 21/22). -
The Foo project releases the
Universal Foo
wide-coverage font family. To allow installing only part of this family, it splits it inUniversal Foo
,Universal Foo Hebrew
andUniversal Foo Thai
. The fontconfig rules forUniversal Foo
MUST rewrite thefamily
(and thereforefullname
) for allUniversal Foo Hebrew
andUniversal Foo Thai
font files, so they declareUniversal Foo
instead. Fontconfig will present the result as a single wide-encoding family to applications, even if the files remain split on-disk, even if all of them are not installed. -
The Foo project releases
Foo Sans
. The fontconfig rules forFoo Sans
SHOULD declare any missing glyph can be taken from thesans-serif
generic font family. -
The GNOME project releases the
Bitstream Vera
set of font families; later theDejaVu
project forks and extends those fonts. The fontconfig rules forDejaVu Sans
SHOULD declare it can be substituted forBitstream Vera Sans
. -
Microsoft ships Windows with the
Arial
font family. Due to its long and wide availability,Arial
is now used in many documents. However it can not be included in Free Desktop systems for licensing reasons. Red Hat commissions anArial
substitute,Liberation Sans
, for use on Linux. Google commissions anotherArial
substiture,Arimo
, for use on ChromeOS. The fontconfig rules forLiberation Sans
SHOULD declare it can be substituted for bothArial
andArimo
.
Style naming
The OpenType specification, the CSS specification and the fontconfig manual document the canonical mappings of style keywords.
Those mappings are not absolute. The addition of variable capabilities enabled the creation of new keywords and axes values, including in non variable font files.
Nevertheless, the OpenType specification requires correlating the new capabilities with the traditional keyword scale:
-
an axis step, with a value, close to one of the specification keywords, SHOULD be named with this keyword,
-
a slight deviation from the canonical keyword value, for design reasons, is expected and accepted.
-
-
an axis step, SHOULD NOT be named with a keyword, when its value differs greatly from the keyword canonical value,
-
font files that define new intermediary steps should also define new keywords.
-
Additionnally:
-
axis keywords SHOULD NOT use whitespace, due to software processing constraints,
-
SemiCondensed
is a good keyword;Semi Condensed
— not.
-
-
keywords SHOULD be assembled in
width weight slant
order in style names, for historical reasons,-
with the default
Regular
ommited except when alone.
-
Checking results

Spec template documentation
The fonts-rpm-templates
package contains spec
templates, corresponding to common fonts packaging needs.
Packaging a single font family
This is the simplest packaging pattern, when upstream releases:
-
a single font family,
-
conforming to this guideline’s definition of a font family,
-
in a single dedicated source archive,
-
without any specific difficulty.
Macros and variables
Declaration ordering
Changing the proposed line order will more often than not result in a Be aware that this particular order was selected after reworking a large pool of test files, to maximize commonalities, and reduce divergence between packaging situations. Reordering may still work but the result will be harder to review, refactor, and copy in other |
SRPM generic declarations
This pattern starts with a block of traditional spec
declarations:
Version:
Release:
URL:
Shared font declarations
Then it declares elements, that will be shared by all the packaged font families. Here, we only process one of those, but the block will be at the same place in the other patterns.
%{foundry} |
an optional upstream identifier, when upstream publishes multiple font families, with consistent QA rules. Font families released by the same upstream will usually play well with one another. Marking them as such helps users choose good font package sets.
|
%{fontlicense} |
the identifier of the font family license, according to our licensing rules. |
Those identifiers are followed by variables, containing:
-
lists of space-separated shell globs,
-
matching the files associated with the font family,
-
as they exist in the build root at the end of the
%build
stage.
%{fontlicenses} |
the font family legal files |
%{fontdocs} |
the font family documentation files |
%{fontdocsex} |
exclusions from the |
%global foundry SIL
%global fontlicense OFL
%global fontlicenses OFL.txt
%global fontdocs *.txt
%global fontdocsex %{fontlicenses}
Family-specific font declarations
This is followed by a family-specific declaration block.
%{fontfamily} |
the human-friendly font family name, whitespace included, restricted to the Basic Latin Unicode block. |
%{fontsummary} |
the generated font package summary. It must be less than 80 columns in length. |
This block contains its own shell glob lists.
%{fonts} |
the font family font files |
%{fontconfs} |
the font family fontconfig files |
Followed by:
%{fontdescription} |
a multi-line description block for the generated package. Each line should be less than 80 columns in length. |
%global fontfamily Andika
%global fontsummary SIL Andika, a font family for literacy and beginning readers
%global fonts *.ttf
%global fontconfs %{SOURCE10}
%global fontdescription %{expand:
Andika is a sans serif, Unicode-compliant font family designed especially for
literacy use, taking into account the needs of beginning readers. The focus is
on clear, easy-to-perceive letterforms that will not be readily confused with
one another.}
Source declarations
Then package sources are declared the usual way.
Source:
Source10: [number]-%{fontpkgname}.conf
Keeping fontconfig file names in sync with the package name is a good idea. Take a look at the templates in fonts-rpm-templates
for information on how to write good fontconfig files and choose the correct priority [number]
.
Font package names
Font package names will be automatically computed from the previous declarations, and put into the |
Remainer of the spec file
All those declarations are used and processed in the rest of the spec
file by the following macros:
%fontpkg |
generate font package headers |

are applied to all font families,
-
unless overriden by the same variable, suffixed with a specific block number
-
for example
%{fontdocs2}
A variable, can be used to share a description block:

%global fontconfs2 %{SOURCE12}
%global fontdescription2 %{expand:
%{common_description}
This package provides the grotesque sans-serif fixed-width IBM Plex Mono, a
little something for developers, because monospace does not need to be monotone.}
Family-specific font declarations
-
each font family is declared in a separate family-specific block,
-
each block is identified by a number, suffixed to the corresponding block variables,
-
for example
%{fontfamily1}
-
-
the zero-suffix block is used to generate SRPM metadata,
-
all the zero-suffix variables are aliased to no-suffix variables of the same name, and vice versa.
Packaging macros
-
%fontpkg
,%fontbuild
,%fontinstall
,%fontcheck
and%fontfiles
accept the following arguments:-
-a
process everything -
-z [number]
process the[number]
declaration block
-
-
if no flag is specified they will only process the zero/no-suffix block
-
consequently, packaging multiple font families will usually require the
-a
option
-
%{\fontmetapkg} |
generate font package headers. Optional arguments (usually unnecessary):
|
%fontmetapkg -z 1,2,3
%global lgcmetasummary All the font packages, generated from %{name}, Latin-Greek-Cyrillic subset

Packaging font families, released as part of something else
The last pattern concerns the packaging one or several font families from a source rpm which is not named after the first packaged font family:
-
either because the project name differs from the main font family name,
-
or when the source archive and rpm are used to package more than fonts.
It is almost identical to the previous one.

Rationale
Legal
Fonts are subject to specific copyright, trademark and patent laws. Reading our fonts legal page is recommended.
Packaging unit: an ideal font family
Font upstreams will often deviate from the OpenType model in their naming:
-
because mistakes happen,
-
because font formats are complex, with a long history, and a huge amount of legacy compability bagage,
-
because upstreams may focus on the artistic side of font creation, to the detriment of its technical side,
-
because upstreams may attempt to workaround problems in the legacy proprietary applications available on their platform of choice,
-
because upstreams may be dormant, and miss changes in the OpenType specification, or use font creation tools that have still not implemented those changes.
Those deviations occur in upstream file names and upstream font file metadata. Upstream choices in those elements can not be relied upon to define useful and consistent font family boundaries.
Shared font files, are no place to workaround application-specific problems. Fedora must apply the OpenType standard strictly, to enable the leveraging by Free Desktop applications, of the application capabilities this standard was designed to unlock. One can always find bits of code not updated to take into account decades-old changes in font standards. Waiting on this code to be fixed is being last, not First.
Font file formats
OpenType highlights
Variable fonts
Application support for variable fonts is sparse right now. They can not replace older OpenType formats yet.
TT versus CFF
-
OpenType TT boasts hinting capabilities, but hinting is labor-intensive and does not scale to large-encoding fonts. In practice modern TT fonts are hinted using automated processes similar to the auto-hinter present in freetype.
-
OpenType CFF lacks hinting but uses the excellent rasterizer Adobe contributed to freetype, achieving similar results.
-
Low-resolution rendering is increasingly irrelevant with the replacement of 96dpi screens by 4K+ HiDPI hardware.
Therefore, don’t use hinting as a format selection criterium, unless you’re sure a human actually proofed the result on a modern renderer, at the screen pixel densities exercised by Fedora users.
Choose the OpenType format best supported upstream, typically the one produced by upstream’s preferred font creation toolchain. For historical reasons the math behind OpenType TT and OpenType CFF differs, converting from one to the other may introduce corner cases problems.
Collections
While collection formats save some storage space, they introduce a high level of complexity packaging and application-side, make it impossible to install font families separately, and create a user-unfriendly environment.
Avoid packaging *.ttc
and *.otc
files unless left no choice by upstream.
Legacy deprecated formats
Legacy formats are too limited to handle Unicode-level coverage, fail to declare their encoding, do not permit the kind of style selection expected in modern fonts, do not provide human-friendly naming layers, etc. They’re full of quirks and a source of (security) bugs in applications.
In 2006, at the first Text Layout summit, all the major Free Desktop players agreed to converge on a unified text layout engine, built around the HarfBuzz project and the OpenType format. As a result, modern Free Desktop applications and libraries no longer support other formats.
Use tools like fontforge or fonttosfnt (provided by xorg-x11-font-utils) to convert legacy fonts to an OpenType format. Get it done upstream or script it within the %build
section of your spec
file.
Like any other format conversion it will need some proofing. That’s why packaging fonts in a single correct format is a requisite for reliable text rendering.
Web fonts
Due to the limitations of the browsers that existed at the time, and due to the fear foundries had of widespread font piracy, initial support for web fonts used a hodgepole of obscure, broken and incomplete font formats (svg
, eot
, woff
, etc).
All major browsers have been fixed long ago to accept OpenType fonts.
Do not package web fonts except in OpenType format. If your upstream still religiously cargo-cults other formats in its CSS files, get those fixed.
The only remotely useful web font format is woff
. Its advantages compared to OpenType are marginal at best on a well-configured web server. The sole remaining reason for woff
existence is to serve as a light form of DRM for proprietary fonts (Normal applications do not read woff
files). That concern does not apply to Fedora. Fedora wants to share. Any so-called web font can be useful in other parts of the distribution. That requires distributing fonts in a common generic format.
Postscript fonts
The OpenType CFF outline format is derived from the one used in Postscript. It was designed by Adobe to permit lossless conversion of legacy Postscript fonts. The SFNT container used by OpenType is vastly more capable than the original PostScript format.
Therefore, there’s no risk, and lots of advantages, in converting Postscript fonts. If their upstream does not want to bother, do not bother packaging the result.
X11 core fonts
Once upon a time every Linux GUI application used the so-called Core fonts server-side X11 backend [1]. It was riddled with problems. The FLOSS developers finally gave up on it, declared it legacy and broken by design, and moved to client-side font handling (fontconfig). Nowadays almost no modern Linux GUI application uses the Core fonts backend. Few (if any) people are willing to fix its remaining bugs.
Therefore, unless your font has previously been registered in Core fonts, and the problems triggered by this font hopefully fixed, you SHOULD NOT declare it there. This is especially true of fonts in modern OpenType formats.
The users of this legacy backend won’t thank you for destabilizing it with new fonts. They value stability. Otherwise they’d have moved to fontconfig like everyone else a long time ago.
Fontconfig
Free Desktop systems rely on multiple upstreams to provide their fonts. They are heavily dependent on fontconfig to present a consistent user-friendly font pool in applications. High quality fontconfig rules are indispensable to permit easy substitution of font families, and to mask upstream messiness.
Applying strict WWS rules helps applications identify all the parts of a font family, and makes selectors like bolder possible.
Removing format attributes from family
prevents breakage, when the technical format shipped by the distribution changes after an update. Because font technology continues to improve, format changes are bound to happen sooner or later. Applications can still request font format information via the fontconfig API if they need to.
Removing coverage attributes from family
enables merging all matching files in a single synthetic family. That is more user friendly, and prevents breakage when upstream decides to split the font family over different lines. Because creating a wide-coverage font family is a hard, long-term endeavour — Unicode is not finalized yet — such changes are common.
The other decisions are just choosing good defaults for the font family. While fontconfig can take a guess at those, its guess will never be as accurate as packager decisions. Packagers can ask upstream for clarifications. Fontconfig can not.
Remember that a lot of upstream naming decisions are taken to accomodate systems, that are missing an automatic font substition / font merging layer. The format and coverage information in family
names is intended to help manual selection of font files. Our guidelines ask packagers to convert those to information fontconfig understands. Free Desktop systems can do a lot more, as long as the information provided to fontconfig is correct.
Source (SRPM) package break-up
As noted in the Packaging Guidelines, Fedora packages should make every effort to avoid having multiple, separate, upstream projects bundled together in a single package. This applies equally to font packages.
Multi-source packages are difficult to maintain and confusing to users.
Installation (RPM) package break-up: font packages
Once all the preceding has been done, a font package should only contain:
-
OpenType font files,
-
in a single OpenType format,
-
baring coverage constrains.
-
-
with WWS-compliant
style
values, -
sharing the same
family
value,-
except for optical sizing atttibutes, which are appended to the common
family
root.
-
-
fontconfig files,
-
appstream files,
-
legal files,
-
documentation files.
Building
Building from source ensures it will be possible to modify the font when problems are reported and upstream is not responsive. Sometimes that means working with upstream to sanitize its build processes.
Packaging a font family in multiple OpenType formats; application support
Fonts are comparatively bulky. Shipping fonts in multiple formats makes the situation worse on user systems, mirrors and live images. Every font family that ships in multiple formats, consumes space that could be used by another font package, enhancing the user experience.
Because applications will make different choices in presence of multiple formats for the same font family, because different formats use different rasterization engines, because format conversions can introduce artefacts, shipping multiple formats reduces the effectiveness of Fedora QA.
Most applications in Fedora support indifferently all OpenType formats,
Most fonts in Fedora are only available in a single OpenType format,
Rendering text in all the locales supported by Fedora requires using multiple fonts in multiple formats,
Therefore packaging a font family in multiple OpenType formats should only be done as a limited exception.
