Will this open the way for multi-language support, or does this only apply to the realm of English?
I think there have been at least Chinese and Russian mods, with their respective fonts.
Naturally, that requires both modding the font file AND tweaking text strings inside game files.
It is a lot of work, runs a risk of breaking the game engine, and won't necessarily work with each new version release. So I have no idea if any of those fan-translated unofficial versions are up to date, nor if they are available somewhere in the net.
