iswpunct - test for punctuation or symbolic wide character
#include <wctype.h>
int iswpunct (wint_t wc);
The iswpunct function is the wide-character equivalent of the ispunct
function. It tests whether wc is a wide character belonging to the wide
character class "punct".
The wide character class "punct" is a subclass of the wide character
class "graph", and therefore also a subclass of the wide character
class "print".
The wide character class "punct" is disjoint from the wide character
class "alnum" and therefore also disjoint from its subclasses "alpha",
"upper", "lower", "digit", "xdigit".
Being a subclass of the wide character class "print", the wide character
class "punct" is disjoint from the wide character class "cntrl".
Being a subclass of the wide character class "graph", the wide character
class "punct" is disjoint from the wide character class "space" and
its subclass "blank".
The iswpunct function returns non-zero if wc is a wide character
belonging to the wide character class "punct". Otherwise it returns
zero.

ispunct(3), iswctype(3)
The behaviour of iswpunct depends on the LC_CTYPE category of the current
locale.
This function's name is a misnomer when dealing with Unicode characters,
because the wide character class "punct" contains both punctuation
characters and symbol (math, currency, etc.) characters.
