[Wine] Problem with japanese programs

[kaeza]

Hello.
I have a tiny problem.
I am running Character Maker (a japanese painting program aimed mainly for RPG Maker and the like).
Now on Windows, it used the default system font, but when I run it under Wine it uses an ugly handwriting font.
Is there a way to fix this problem?
It also happens with several programs which were originally in japanese (such as Melody Raiser [from the same author] and PSX Multi Converter [A program to play music videos and view images from Playstation CDs]).
