Hello Thomas, Oops 1: I forgot to add the reference to POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswcntrl.html
Oops 2: The relevant expression is iswcntrl (WEOF), not iswcntrl (EOF). > > Are there any other special requirements concerning EOF? WEOF is a special value. The difference between wint_t and wchar_t is essentially that WEOF fits into wint_t but is not guaranteed to fit in wchar_t. (Like EOF fits into 'int' but usually does not fit in 'unsigned char'.) WEOF is special for all functions declared in <wctype.h>, see http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswalnum.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswalpha.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswblank.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswcntrl.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswdigit.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswgraph.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswlower.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswprint.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswpunct.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswspace.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswupper.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswxdigit.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/iswctype.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/towlower.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/towupper.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/towctrans.html > this could be fixed in iswcntrl_l.c as a special condition, or > injected as a special case in the categories.t table.
