Hi, I need to run a gtk program in a UTF-8 locale. When i try to, I get the error:

Gtk-WARNING **: locale not supported by C library.
Using the fallback 'C' locale.

I have looked at other posts about this and have read a few different things (that I need to rebuild glibc or something like that. But I have a more conceptual question about this.

Does anyone know what the actual problem is rather than what I need to do to fix it (not that i dont want to know how to fix it too)? What I mean is, does this warning mean that i have a problem with my locales, gtk, ect.

If anyone could shed some light on the situation, I'd really appreciate it. Thanks!

From what it sounds like your computer may just be complaining about semantics... UTF-8 and standard 7-bit ASCII encode characters with exactly the same numeric values but glibc by default uses ASCII (as defined in c-cctype.c) to represent characters. So the problem seems to be that the files could be said to be in either encoding (since they are equivalent), UTF-8 is technically not ASCII and computers don't usually respect equivalence (it's either equal or it's an error in this case). So, changing c-ctype.c to use UTF-8 and recompiling glibc will fix the "problem" that technically isn't even one in the first place...

Sorry about the delayed response and thanks. a few minor changes and a recompile fixed the problem.
