Description
This feature provides a tool for customizing fonts per language on desktops using fontconfig. The user requirements of desktop fonts are diverse, no single configuration can satisfy all user requirements.
How to test
- dnf install fonts-tweak-tool
- Run fonts-tweak-tool
- Try to set some preferred fonts for a particular language
- Check the generated font configuration 000-fontstweak-ezfc.conf in $HOME/.config/fontconfig/conf.d/
- Test rendering of text for that language/locale in gedit etc.
- Test fc-match:
- fc-match sans-serif:lang=<target language like en and zh-cn>
- fc-match serif:lang=<target language like hi-in and ja>
- fc-match monospace:lang=<target language like fr and pt-br>
Expected Results
The font that you specified with fonts-tweak-tool should be used for that language.
