iswgraph - test for graphic wide character
#include <wctype.h>
int iswgraph(wint_t wc);
The iswgraph() function is the wide-character equivalent of the
isgraph(3) 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".
The wide-character class "graph" contains all the wide characters
from the wide-character class "print" except the space character. It
therefore contains the wide-character classes "alnum" and "punct".
The iswgraph() function returns nonzero if wc is a wide character
belonging to the wide-character class "graph". Otherwise, it returns
zero.
For an explanation of the terms used in this section, see
attributes(7).

The behavior of iswgraph() depends on the LC_CTYPE category of the
current locale.
