I've never worked with that format before and I can't find any way to test it, if you could help me testing it send me a DM through twitter that'd be great and then I could include it!
Sorry, i dont use X. What about instagram or discord. I can test it with the game engine that im using. The Game engine that im using “Gdevelop” requires .fnt and atlas image of the font to be able to used as bitmap font.
