Over on Hexoshi’s GitLab page, I and a volunteer have been working on extending Hexoshi’s font to support accented characters. As of today, most of the major characters are now available for translations, although most of them just look like their nearest unaccented equivalents. This will be worked on in the coming days.
It’s technically possible to also add non-European languages to Hexoshi’s font. However, since each character has to be manually added in, it’s unlikely that full support will be feasible for many non-European languages. Still, if you are doing a translation for Hexoshi and need to use non-Latin characters, feel free to add them in and submit a pull request! :) I would also appreciate additional help putting the actual accents on accented Latin characters.
