Hungarian translation


I would like to make a Hungarian translation for Kudos 2. I have already found the files that contain the in-game text, but I have one problem. The fonts included in the game don’t contain any Hungarian accented letters. (So the fonts don’t contain the following characters: öÖ üÜ óÓ őŐ úÚ éÉ áÁ űŰ íÍ)
Is it possible to modify the fonts used by the game?
