N869
7.4 Character handling <ctype.h>
       In all cases the
       argument is an int, the value of which shall be
       representable as an unsigned char or shall equal the value
       of the macro EOF. If the argument has any other value, the
       behavior is undefined.

Negative values aren't representable as unsigned char.
