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.  :)
