Apparently Terminal.app won't set LANG to a locale that's not in /usr/ 
share/locale.

I'm not sure what you mean here.  Are you referring to the general  
Unix meaning of these variables or Wine's use of them?

As near as I can tell, Wine only probes the locale information by  
invoking setlocale(<category>, NULL).  It doesn't directly examine the  
environment variables.  Furthermore, it only queries using the  
individual categories, not LC_ALL.  It uses setlocale(LC_ALL, "") once  
to tell the C library to initialize itself from the environment.

So, I'm not sure how setting all of the LC_* variables to a given  
value can be different from setting LC_ALL to that value.

Maybe Terminal.app is setting LC_CTYPE when it can't set LANG.  Check  
what's actually set in your environment:

env | egrep "^(LANG|LC_)"
