iswprint - test for printing wide character
int iswprint(wint_t wc);
The iswprint() function is the wide-character equivalent of the isprint(3) function. It tests whether wc is a wide character belonging to the wide-character class "print".
The wide-character class "print" is disjoint from the wide-character class "cntrl".
The wide-character class "print" contains the wide-character class "graph".
The iswprint() function returns nonzero if wc is a wide character belonging to the wide-character class "print". Otherwise, it returns zero.
For an explanation of the terms used in this section, see attributes(7).
