std::iswpunct(3)	      C++ Standard Libary	      std::iswpunct(3)

NAME
       std::iswpunct - std::iswpunct

Synopsis
	  Defined in header <cwctype>
	  int iswpunct(	std::wint_t ch );

	  Checks  if the given wide character is a punctuation character, i.e.
       it is one of
	  !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ or any punctuation  character  spe-
       cific to	the
	  current locale.

	  If  the  value of ch is neither representable	as a wchar_t nor equal
       to the value of
	  the macro WEOF, the behavior is undefined.

Parameters
	  ch - wide character

Return value
	  Non-zero value if the	wide character	is  a  punctuation  character,
       zero otherwise.

Notes
	  ISO  30112  specifies	 which Unicode characters are include in POSIX
       punct category.

Example
       // Run this code

	#include <iostream>
	#include <cwctype>
	#include <clocale>

	int main()
	{
	    wchar_t c =	L'\u2051'; // Two asterisks ('')

	    std::cout << std::hex << std::showbase << std::boolalpha;
	    std::cout << "in the default locale, iswpunct(" <<	(std::wint_t)c
       << ") = "
		      << (bool)std::iswpunct(c)	<< '\n';
	    std::setlocale(LC_ALL, "en_US.utf8");
	    std::cout  <<  "in Unicode locale, iswpunct(" << (std::wint_t)c <<
       ") = "
		      << (bool)std::iswpunct(c)	<< '\n';
	}

Output:
	in the default locale, iswpunct(0x2051)	= false
	in Unicode locale, iswpunct(0x2051) = true
