true, but European is a subset of international.

Not true at all.  "isalpha", "isupper", and most of the others are explicitly
NOT ASCII dependent.  They exist to allow independence from ASCII.  Sure, they
are implemented in an ASCII-dependent way, but if you want to change the
charset, all you need to do is change ctype.h and the library routine(s) (if
any).  In fact, for one of the implementations of ctype.h, all you need to
do is to change a table of character types.
