It surely would help if you would try this in an Objective-C only
application, but in this specific case it looks like a real GNUstep
problem. :-)
You did not state the environment you are running on, but from C# and
the font name I suspect that you are on MS Windows. I would thing that
the problem you get comes from [Win32FontInfo setupAttributes]
where the
code expects to be able to call cString on the font family name and
this
fails for your Asian font name. Again a full back trace in gdb would
have been helpful.
The only solution I can see for this problem, if I did identify it
correctly, is to switch our whole Win32 code over to use what
Microsoft
calls UNICODE, that is 16 bit w_char instead of char. As I have
given up
Microsoft Windows programming years ago, we will have to look for a
new
volunteer to do this.
I've converted the font handling (I hope) to use the wide version of
the API.
The new code is in subversion (trunk). I only addressed the font
handling code, and there are undoubtedly other areas where unicode we
still need to convert to unicode.
Incidentally, what Microsoft call UNICODE is pretty much the same as
what OpenStep/GNUstep/Cocoa calls NSUnicodeStringEncoding.
That is to say it is UTF-16 encoding ... most characters fit in a
16bit value, but a few take up more room and are represented as
'surrogate pairs'. However, the two halves of a surrogate pair are
usually treated as separate characters. They are certainly treated
as such for purposes of determining a string length (which is the
number of 16bit values in the string).
