--- Comment #22 from Michal Suchanek hramrach@centrum.cz 2009-04-27 05:57:55 --- ok, with Wine 1.1.19 the font link works although the text looks really ugly (anybody tried regedit in ja_JP.UTF-8 ?).
Interestingly it is possible to write Japanase in en_US.UTF-8 which should not be possible (the initial text is garbled, though, as expected).
So there is likely another issue.
