       The iswpunct() function is the wide-character equivalent of the ispunct(3) 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".

       iswpunct - test for punctuation or symbolic wide character

       The behavior 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.

       The  iswpunct()  function returns nonzero if wc is a wide-character belonging to the wide-character class
       "punct".  Otherwise, it returns zero.
