My Mac OS installations do not have LC_ALL.

But I just noticed that Carbon GUI programs do not get LC_CTYPE in their
environment either.

So maybe cwstring needs to be fixed for Carbon GUI Mac OS X programs.

What I see in the environment is
__CF_USER_TEXT_ENCODING=0x1F5:0x0:0x0

I think Carbon apps should override DefaultSytemCodePage, because the
Carbon interfaces always use UTF-8, they do not care about any
environment strings.

Cheers,
