I bet the Unicode standard has a standard way to do this.  Maybe we
can implement that, and then project the same interface on 8-bit
characters?  Of course character encoding issues might get in the way
if <ctype.h> doesn't provide the data -- so you may be better off
doing this in Unicode only.  (We must never assume that 8-bit strings
contain Latin-1.)
