I recently upgraded a Debian Stretch installation to Buster using the official guide. I just noticed I'm missing some font/icon/glyph on the on/off switches in gnome-control-center. Where the icons should be it shows 23F0 for on and 2858 for off. I tried a couple things, but nothing solved my issue.

  • reinstall gnome-control-center sudo apt install --reinstall gnome-control-center
  • rebuild the font cache sudo fc-cache -f -v
  • Changed the fonts in gnome-tweak.

How can I solve this problem?
