No, it's defined for the entire range of unsigned char.
Note that 'isascii' probably has the same range limit, although it's not a
"C" funcation (it's POSIX) so I don't have the spec handy. I expect it has
the same problem. Hmm. Not in our macro version, anyway:
#define isascii(c) ((unsigned)(c) <= 0177)
I still wouldn't count on it. :)
