So I run LANG=ja_JP.UTF-8 wine testwin.exe which renders expected number of characters but the Japanese ones aren't displayed - only spaces or black squares are rendered instead.
Does Wine notepad show japanese fonts in menus and in the text?
The glyph ranges should be sufficient. The font name is, of course, completely different. But you cannot expect that fonts named MS Mincho, MS Gothic or MS UI Gothic would be installed on all wine setups. These fonts are only available with Windows and cannot be normally obtained separately, unlike the MS Core Fonts.
If a Windows application hard codes font names (which is the case for most Windows applications) missing necessary fonts is fatal.
However, most Japanese font packages provide two font variants that contain Mincho and Gothic at the end of their font name.
That's not enough.
