--- Comment #53 from Rafał Mużyło galtgendo@o2.pl 2011-03-18 17:29:48 CDT --- Well, for the moment, it's hard to tell whether it's the right direction or not. Regardless, thanks for the effort.
Anyway, 1.3.16 offered no changes here, though it improved a different case quite a bit (furigana (at least it seems that's it) isn't displayed there correctly, but at least most of the text is displayed now - still it floods with 'fixme:d3d_surface:IWineD3DBaseSurfaceImpl_Blt Filter WINED3DTEXF_LINEAR not supported in software blit.' but that's a matter for a different bug, should I file one).
Well, uniscribe is a fairly recent addition, before it internationalization on the fonts side had to be lacking.
