  # Note on fonts:
  #
  # OnlyOffice does not distribute unfree fonts, but makes it easy to pick up
  # any fonts you install. See:
  #
  # * https://helpcenter.onlyoffice.com/en/installation/docs-community-install-fonts-linux.aspx
  # * https://www.onlyoffice.com/blog/2020/04/how-to-add-new-fonts-to-onlyoffice-desktop-editors/
  #
  # As recommended there, you should download
  #
  #     arial.ttf, calibri.ttf, cour.ttf, symbol.ttf, times.ttf, wingding.ttf
  #
  # into `~/.local/share/fonts/`, otherwise the default template fonts, and
  # things like bullet points, will not look as expected.

  # TODO: Find out which of these fonts we'd be allowed to distribute along
  #       with this package, or how to make this easier for users otherwise.

  # Not using the `noto-fonts-cjk` package from nixpkgs, because it was
  # reported that its `.ttc` file is not picked up by OnlyOffice, see:
  # https://github.com/NixOS/nixpkgs/pull/116343#discussion_r593979816
