ISWGRAPH (3)
test for graphic wide character
SYNOPSIS
#include <wctype.h>
int iswgraph (wint_t wc );
DESCRIPTION
The iswgraph function is the wide-character equivalent of the
isgraph function. It tests whether wc is a wide character
belonging to the wide character class "graph".
The wide character class "graph" is a subclass of the wide character class
"print".
Being a subclass of the wide character class "print", the wide character class
"graph" is disjoint from the wide character class "cntrl".
The wide character class "graph" is disjoint from the wide character class
"space" and therefore also disjoint from its subclass "blank".
