--- Comment #13 from Michal Suchanek hramrach@centrum.cz 2008-06-04 15:11:30 --- fwiw with Windows fonts the application shows black squares instead of empty spaces where the Japanese characters should be.
However, there is no point in using Windows fonts here. There are several fonts that would cover all characters that can be encoded in EUC_JP in the system already.
