--- Comment #3 from Rafał Mużyło galtgendo@o2.pl --- Well, my point was slightly different than your take of it.
I was addressing only the part 'Problem with the Workaround', nothing else.
Given that in my personal experience many Japanese programs require FontSubstitutes entries for MS Gothic/Mincho for proper font display, setting them up is only an issue that wine doesn't set them up automatically (and it shouldn't - that font should be user's choice). I have those and they don't interfere with font display in other locales.
IIRC, I've never tinkered with FontLink setting, so no idea about that topic.
