Ok, I'll need a test application for that. There's no way to guess what breaks
exactly in your case. In my testing Japanese text in winecfg is displayed as it
should. Also it's possible that your application depends on particular font to
render Japanese, and when running on wine it ends up using some other one from
your system.
