Honestly I have no idea what i did. But this is certainly useful. It makes all the Asian symbols: hiragana, katakana, kanji, whatever other Chinese/Korean you have. All your normal Latin symbols still work well.
Known bugs: -when actually installing the font the letters are still sideways, import this font in included files. -somehow game maker imports the ENTIRE character range. all characters creating some loading time and memory consumption. BE SURE TO CALL FONT_DELETE AFTER USE.
I might add other fonts in the future, but only if i figure out what i actually did. when i try to reproduce what i did the fonts end up not working at all. Basically i imported it in a program called font creator, did something and than saved it again and it fixed itself. Although this is not high quality market stuff, it should be useful to at least someone.
