setlocale (was: curses vs non-ASCII)

That's odd. If you didn't call setlocale() at all, the C library should 
have been using the "C" locale, which doesn't have multi-byte characters. 
Does some library you linked in call setlocale()?

I dimly remember that (at least in ncursesw) there may have been some 
additional magic handling 00-1F and 80-9F.
