Test for printing wide character
#include <wctype.h> 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.
C99.
The behavior of iswprint() depends on the LC_CTYPE category of the current locale.
