Remove system fonts which are useful for your case
Collabora Online uses system-installed fonts. If you’d like to limit available fonts further, you can uninstall unnecessary fonts from your system.
Use a Custom Font Directory
If you only want specific fonts to be available, you can configure Collabora to use a custom directory for fonts by modifying the <fontdir> setting in the coolwsd.xml file.
- First, move the fonts you want to keep into a custom directory, e.g.,
/usr/local/share/fonts/custom. - Then, add the path to the font directory in
coolwsd.xml:
<fontdir path="/usr/local/share/fonts/custom" />
