There is a texture named font.dds and it contains characters of various writing systems. If your translated lines do not show up, then there is a chance your characters are not supported. There is a way to add them though by modding.
I'm trying to add Georgian. I checked out the font file and it seems complicated, is there any tutorial or guide somewhere on the internet i can follow to edit it properly?
Basically i am adding my native language to the game, but it has an entirely different writing system so when i load up the game everything that i translated shows up blank. Does anyone know how to add the font specific to my language?
