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

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

	  std::cout << std::hex << std::showbase << std::boolalpha
		    << "in the default locale, iswpunct("
		    << static_cast<std::wint_t>(c) << ") = "
		    << static_cast<bool>(std::iswpunct(c)) << '\n';

	  std::setlocale(LC_ALL, "en_US.utf8");
	  std::cout << "in Unicode locale, iswpunct("
		    << static_cast<std::wint_t>(c) << ") = "
		    << static_cast<bool>(std::iswpunct(c)) << '\n';
      }

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