[SOLVED] Adding 'Noto Sans Sinhala' as the system default Sinhala font

dhplakmal · 2022-03-21 05:33:33

Hello,
I'm trying to change the default LKLUG Sinhala font to Noto Sans Sinhala because LKLUG is a bit outdated and also difficult to read web content with that font. I tried messing around with the user font config file ($HOME/.config/fontconfig/fonts.conf) but no luck. It does apply the font but partially. What I mean is after the conf change when I browse the web, part of the Sinhala content is still rendered in LKLUG some parts are in Noto Sans Sinhala. Not consistent (tested on both Firefox and Brave, behaviour is same on both browsers). I would like to know a way to fix this if anyone knows.

This is the content of my "$HOME/.config/fontconfig/fonts.conf" file.

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<match target="pattern">
 <test name="lang" compare="contains">
  <string>si</string>
 </test>
 <edit mode="prepend" binding="strong" name="family">
  <string>Noto Sans Sinhala</string>
 </edit>
</match>
<dir>~/.fonts</dir>
</fontconfig>

language tests aren't reliable, https://wiki.archlinux.org/title/Font_c … les#Arabic

The above should work for most applications but some applications like Chromium do not work with the language match test. If you find some applications not using your selected fonts, you can use the below alias and prefer tags which seems to work.

Thanks, tried the one with the alias and prefer tags, provided on the wiki. This time the results are somewhat better. Now 95% is rendered with the desired font and the rest is still rendered with the same old font. (Previously it was like 70% & 30%).

fc-match -s ':charset=1234'
fc-list ':charset=1234'

Replace "1234" w/ the actual utf-8 codepoint of a glyph that isn't resolved to Noto Sans Sinhala (sould be some 0dxx, https://en.wikipedia.org/wiki/Sinhala_(Unicode_block) )

I combined both types of configs (alias prefer and select) as below. Now I'm getting the output I wanted. Thanks

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
