From Wikipedia:Computer font:

A computer font is implemented as a digital data file containing a set of graphically related glyphs. A computer font is designed and created using a font editor. A computer font specifically designed for the computer screen, and not for printing, is a screen font.

Note that certain font licenses may impose some legal limitations.

Font formats

Most computer fonts used today are in either bitmap or outline data formats.

Bitmap fonts
Consist of a matrix of dots or pixels representing the image of each glyph in each face and size.
Outline or vector fonts
Use Bézier curves, drawing instructions and mathematical formulae to describe each glyph, which make the character outlines scalable to any size.

Bitmap formats

These formats can also be gzipped. See #Bitmap for the available bitmap fonts.

Outline formats

  • PostScript fonts by Adobe – has various formats, e.g: Printer Font ASCII (PFA) and Printer Font Binary (PFB)
  • TrueType by Apple and Microsoft (file extension: ttf)
  • OpenType by Microsoft, built on TrueType (file extensions: otf, ttf)

For most purposes, the technical differences between TrueType and OpenType can be ignored.

Other formats

The font editing application FontForge (fontforge) can store fonts in its native text-based format—Spline Font Database (.sfd).

The typesetting application TeX Live and its companion font software Metafont traditionally renders characters using its own methods. Some file extensions used for fonts from these two programs are *pk, *gf, mf and vf. Modern versions can also use TrueType and OpenType fonts.

The SVG format also has its own font description method.

Installation

There are various methods for installing fonts.

Pacman

Fonts and font collections in the enabled repositories can be installed using pacman.

Available fonts may be found by querying packages (e.g. for font or ttf).

Creating a package

You should give pacman the ability to manage your fonts, which is done by creating an Arch package. These can also be shared with the community in the AUR. The packages to install fonts are particularly similar; see Font packaging guidelines.

The family name of a font file can be acquired with the use of fc-query for example: fc-query -f '%{family[0]}\n' /path/to/file. The formatting is described in FcPatternFormat(3).

Manual installation

The recommended way of adding fonts that are not in the repositories of your system is described in #Creating a package. This gives pacman the ability to remove or update them at a later time.

Alternatively, fonts can be installed manually:

  • For a single user, install fonts to ~/.local/share/fonts/.
    • In many cases this suffices, unless you run graphical applications as other users.
    • In the past ~/.fonts/ was used, but is now deprecated.
  • For system-wide (all users) installation, place your fonts under /usr/local/share/fonts/.
    • You may need to create the directory first: mkdir -p /usr/local/share/fonts.
    • /usr/share/fonts/ is under the purview of the package manager, and should not be modified manually.

The creation of a subdirectory structure is up to the user, and varies among Linux distributions. For clarity, it is good to keep each font in its own directory. Fontconfig will search its default paths recursively, ensuring nested files get picked up.

An example structure might be: 

/usr/local/share/fonts/
├── otf
│   └── SourceCodeVariable
│       ├── SourceCodeVariable-Italic.otf
│       └── SourceCodeVariable-Roman.otf
└── ttf
    ├── AnonymousPro
    │   ├── Anonymous-Pro-B.ttf
    │   ├── Anonymous-Pro-I.ttf
    │   └── Anonymous-Pro.ttf
    └── CascadiaCode
        ├── CascadiaCode-Bold.ttf
        ├── CascadiaCode-Light.ttf
        └── CascadiaCode-Regular.ttf

The font files need to have sufficient read permissions for all users, i.e. at least chmod 444 for files, and 555 for directories.

For the Xserver to load fonts directly (as opposed to the use of a font server), the directory for your newly added font must be added with a FontPath entry. This entry is located in the Files section of your Xorg configuration file (e.g. /etc/X11/xorg.conf or /etc/xorg.conf). See #Older applications for more detail.

Finally, update the Fontconfig cache (usually unnecessary as software using the Fontconfig library does this): 

$ fc-cache

Older applications

With older applications that do not support Fontconfig (e.g. GTK 1.x applications, and xfontsel) the index will need to be created in the font directory: 

$ mkfontscale
$ mkfontdir

Or to include more than one folder with one command: 

$ for dir in /font/dir1/ /font/dir2/; do xset +fp $dir; done && xset fp rehash

Or if fonts were installed in a different sub-folders under the e.g. /usr/share/fonts: 

$ for dir in * ; do if [  -d  "$dir"  ]; then cd "$dir";xset +fp "$PWD" ;mkfontscale; mkfontdir;cd .. ;fi; done && xset fp rehash

At times the X server may fail to load the fonts directory and you will need to rescan all the fonts.dir files: 

# xset +fp /usr/share/fonts/misc # Inform the X server of new directories
# xset fp rehash                # Forces a new rescan

To check that the font(s) is included: 

$ xlsfonts | grep fontname
Note: Many packages will automatically configure Xorg to use the font upon installation. If that is the case with your font, this step is not necessary.

This can also be set globally in /etc/X11/xorg.conf or /etc/X11/xorg.conf.d.

Here is an example of the section that must be added to /etc/X11/xorg.conf. Add or remove paths based on your particular font requirements. 

# Let X.Org know about the custom font directories
Section "Files"
    FontPath    "/usr/share/fonts/100dpi"
    FontPath    "/usr/share/fonts/75dpi"
    FontPath    "/usr/share/fonts/cantarell"
    FontPath    "/usr/share/fonts/cyrillic"
    FontPath    "/usr/share/fonts/encodings"
    FontPath    "/usr/share/fonts/misc"
    FontPath    "/usr/share/fonts/truetype"
    FontPath    "/usr/share/fonts/TTF"
    FontPath    "/usr/share/fonts/util"
EndSection

Pango warnings

When Pango is in use on your system it will read from Fontconfig to sort out where to source fonts. 

(process:5741): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='common'
(process:5741): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'

If you are seeing errors similar to this and/or seeing blocks instead of characters in your application then you need to add fonts and update the font cache. This example uses the ttf-liberation fonts to illustrate the solution (after successful installation of the package) and runs as root to enable them system-wide. 

# fc-cache
/usr/share/fonts: caching, new cache contents: 0 fonts, 3 dirs
/usr/share/fonts/TTF: caching, new cache contents: 16 fonts, 0 dirs
/usr/share/fonts/encodings: caching, new cache contents: 0 fonts, 1 dirs
/usr/share/fonts/encodings/large: caching, new cache contents: 0 fonts, 0 dirs
/usr/share/fonts/util: caching, new cache contents: 0 fonts, 0 dirs
/var/cache/fontconfig: cleaning cache directory
fc-cache: succeeded

You can test for a default font being set like so: 

$ fc-match
LiberationMono-Regular.ttf: "Liberation Mono" "Regular"

Font packages

This is a selective list that includes many font packages from the AUR along with those in the official repositories.

Tip: Archfonts is a Python script that can be used to generate an overview of all the TTF fonts found in the official repositories and in the AUR.

Bitmap

Note: pango 1.44 dropped support for FreeType in favor of HarfBuzz thus losing support for traditional BDF/PCF bitmap fonts, so some applications (e.g. gnome-terminal) will not work with such fonts anymore, showing rectangles instead of glyphs. See FS#63297, Pango issue #386 and HarfBuzz issue #1897.

Emoji and symbols

A section of the Unicode standard is designated for pictographic characters called "emoji".

Emoji fonts come in different formats: CBDT/CBLC (Google), SBIX (Apple), COLR/CPAL (Microsoft), SVG (Mozilla/Adobe).

Emojis should work out of the box once you have at least one emoji font installed of a supported format. However, some of the emoji fonts encode their glyphs as large fixed-size bitmaps and thus, for the purpose of displaying at the intended size, rely on bitmap font downscaling, which is enabled by default.

Emoji font fallback according to the standard requires extra code to handle emoji.

For the discovery and input of Emoji see List of applications/Utilities#Text input.

Software CBDT/CBLC SBIX COLR/CPAL SVG Emoji font fallback
FreeType Yes Yes Yes No –
Chromium FreeType – Yes
Firefox FreeType Yes No, see Firefox#Font troubleshooting for workaround.
Pango FreeType – Yes
Qt FreeType – No [1] [2] [3]
WebKitGTK FreeType – Yes
Note: Qt can only use first 255 fonts at a time [4]. Make sure you have an emoji font in your list of preferred fallback fonts.

Kaomoji are sometimes referred to as "Japanese emoticons" and are composed of characters from various character sets, including CJK and Indic fonts. The following set of packages covers most of existing kaomoji:

Teranoptia (ttf-teranoptia-furiaeAUR) – is a typeface without letters (an illustrative font), a peculiar contraption that allows you to imagine chimeric creatures just by typing letters with your keyboard.

Math

Additionally, texlive-basic and texlive-fontsextra contain many math fonts such as Latin Modern Math and STIX fonts. See TeX Live#Making fonts available to Fontconfig for configuration.

Font alias

This article or section is a candidate for merging with Fontconfig.

Notes: This section is Fontconfig-specific. (Discuss in Talk:Fonts)

There are several font aliases which represent other fonts in order that applications may use similar fonts. The most common aliases are: serif for a font of the serif type (e.g. DejaVu Serif); sans-serif for a font of the sans-serif type (e.g. DejaVu Sans); and monospace for a monospaced font (e.g. DejaVu Sans Mono). However, the fonts which these aliases represent may vary and the relationship is often not shown in font management tools, such as those found in KDE Plasma and other desktop environments.

To reverse an alias and find which font it is representing, run: 

$ fc-match monospace
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

In this case, DejaVuSansMono.ttf is the font represented by the monospace alias.

Fallback font order

This article or section is a candidate for merging with Fontconfig.

Notes: This section contains Fontconfig-only related information. (Discuss in Talk:Fonts)

Fontconfig automatically chooses a font that matches the current requirement. That is to say, if one is looking at a window containing English and Chinese for example, it will switch to another font for the Chinese text if the default one does not support it.

Fontconfig lets every user configure the order they want via $XDG_CONFIG_HOME/fontconfig/fonts.conf. If you want a particular Chinese font to be selected after your favorite Serif font, your file would look like this: 

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<alias>
   <family>serif</family>
   <prefer>
     <family>Your favorite Latin Serif font name</family>
     <family>Your Chinese font name</family>
   </prefer>
 </alias>
</fontconfig>
Tip:
  • If you use a Chinese locale, set LC_LANG to und to make this work. Otherwise both English and Chinese text will be rendered in the Chinese font.
  • If you want to see a list of fonts against ambiguous patterns (i.e. which might not match exactly) such as a generic family names, you can use fc-match --sort or fc-match --all.
  • fc-match --sort does not show a font if its Unicode coverage is provided by already shown font, see fc-match(1) and FcFontSort(3).
  • After changing the configuration run fc-match --all serif | head to verify your fallback font is set correctly.

You can add a section for sans-serif and monospace as well.

For more information, have a look at the Fontconfig manual. See also Font configuration#Set default or fallback fonts.

Tips and tricks

List installed fonts for a particular language

This article or section is a candidate for merging with Fontconfig.

Notes: This section is Fontconfig-specific. (Discuss in Talk:Fonts)

Applications select and display fonts depending upon Fontconfig preferences and available font glyphs for Unicode text. To list installed fonts for a particular language, issue a command fc-list :lang="two letter language code". For instance, to list installed Arabic fonts or fonts supporting Arabic glyphs: 

$ fc-list -f '%{file}\n' :lang=ar
/usr/share/fonts/TTF/FreeMono.ttf
/usr/share/fonts/TTF/DejaVuSansCondensed.ttf
/usr/share/fonts/truetype/custom/DroidKufi-Bold.ttf
/usr/share/fonts/TTF/DejaVuSansMono.ttf
/usr/share/fonts/TTF/FreeSerif.ttf

List installed fonts for a particular Unicode character

This article or section is a candidate for merging with Fontconfig.

Notes: This section is Fontconfig-specific. (Discuss in Talk:Fonts)

To list all fonts supporting a particular Unicode codepoint—black upwards equilateral arrowhead (⮝) in this case: 

$ fc-list :charset=2B9D

fc-list does not normalize requests, it is going to list fonts which exactly matches. It is not suitable for generic family names (like monospace) and other ambiguous patterns. To search for monospaced fonts supporting a particular Unicode codepoint you could try the following: 

$ fc-match --sort monospace:charset=2B9D | head

but you have to interpret the result on your own. fc-match by its nature does not guarantee that fonts in the output list are monospaced, nor that they contain the codepoint in question at all.

Application-specific font cache

Matplotlib (python-matplotlib) uses its own font cache, so after updating fonts, be sure to remove ~/.matplotlib/fontList.cache, ~/.cache/matplotlib/fontList.cache, ~/.sage/matplotlib-1.2.1/fontList.cache, etc. so it will regenerate its cache and find the new fonts [5].

Bidirectional text support

See Bidirectional text for troubleshooting problems related to RTL languages.

Braille font not displaying correctly inside terminals

If braille characters in terminals exhibit rendering issues, try installing a braille font and uninstalling gnu-free-fonts.

Application-specific font configuration tips

Emacs

Emacs calculates sizes differently than standard Linux desktop applications, and Emacs packages do not all use the same config format, so if points or raw pixel size doesn't work, try using the other value.

Visual Studio Code

Change the setting Editor: Experimental Whitespace Rendering from "svg" to "font" if your monospace fonts have problems scaling certain characters correctly. This is known to help with "Terminus (TTF)" and "IBM 3270" fonts.
