The TTF fonts shipped with Cosmoteer game (Steam Game Id 799600) have some Chineese characters incorrectly rendered
I can't attach the fonts here unfortunately because apparently that is copyrighted material. The example of font is ./Data/gui/play_msyh.ttf in the game installation directory. The problem was originally observed in the game running with Proton when selecting Chineese language, it is immediately seen with 'ftview play_msyh.ttf': many Chineese characters are displayed incorrectly. Disabling hinting fixes the rendering. There are various errors coming from TT interpreter (e. g., Stack_Overflow, Invalid_Reference) when hinting is enabled. The font is rendered fine on Windows. Honestly, I am not sure if those are bugs in the font itself or in freetype interpreter.
