[SOLVED]Non-Latin fonts in Chromium

Inxsible · 2021-04-24 18:31:56

I am trying to set up different fonts for Arabic on my system. I installed the arabeyes font from AUR & I set up a simple $XDG_CONFIG/fontconfig/fonts.conf file to select the Arabic font that I want:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>

<!-- Default font for the ar_AR locale (no fc-match pattern) -->
 <match>
  <test compare="contains" name="lang">
   <string>ar</string>
  </test>
  <edit mode="prepend" name="family">
      <string>Tholoth</string>
  </edit>
 </match>
</fontconfig>

This works great on Firefox, but Chromium will only display the Roya font (which is too small for me to read which is why I want to change it)

I did an fc-match -v sans: lang=ar and it seems to list the correct font as Tholoth

fc-match -v sans:lang=ar

fc-match -s sans shows Roya to be the first that supports Arabic

Same thing happens if I install Noto Fonts and remove Arabeyes -- Then Chromium just uses Noto Sans Arabic and does not allow changing it to anything else. If I install Arabeyes fonts again, Chromium just uses Roya . I read a few links about this and it seems due to Sandboxing Chromium doesn't use fonts from the system : https://dev.chromium.org/developers/linux-technical-faq & on Arch wiki : https://wiki.archlinux.org/index.php/Chromium#Fonts.

So since it doesn't respect the fontconfig, is there any other way to change the fc-match -s sans list to put the desired font as the first available one?

Thanks.

EDIT : Did some more testing and it seems that fc-match -s sans:lang=ar shows me the font that I set as the first one but Chromium is just using the first one available from the fc-match -s sans list and not considering my language match while Firefox is.

How can I change the match filter so that Chromium also acknowledges the language match and accordingly changes the font?

SOLVED --

Fixed it by using the alias instead.

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>


<!-- Fallback fonts preference order -->
 <alias>
  <family>sans-serif</family>
  <prefer>
   <family>Noto Sans</family>
   <family>Open Sans</family>
   <family>Droid Sans</family>
   <family>Roboto</family>
   <family>Tholoth</family>
  </prefer>
 </alias>
 <alias>
  <family>serif</family>
  <prefer>
   <family>Noto Serif</family>
   <family>Droid Serif</family>
   <family>Roboto Slab</family>
   <family>Tholoth</family>
  </prefer>
 </alias>
 <alias>
  <family>monospace</family>
  <prefer>
   <family>Noto Sans Mono</family>
   <family>Droid Sans Mono</family>
   <family>Roboto Mono</family>
  </prefer>
 </alias>

</fontconfig>

This is respected by both Chromium and Firefox -- whereas the match test for language is only respected by Firefox.
