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

NAME
     std::iswgraph - std::iswgraph

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

	Checks	if the given wide character has a graphical representation, i.e.
     it is either
	a number (0123456789), an uppercase letter (ABCDEFGHIJKLMNOPQRSTUVWXYZ),
     a lowercase
	letter (abcdefghijklmnopqrstuvwxyz), a punctuation character
	(!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~) or any graphical  character	specific
     to the
	current C 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  has  a  graphical  representation
     character, zero
	otherwise.

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

Example
     // Run this code

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

      int main()
      {
	  wchar_t c = L'\u2602'; // the Unicode character Umbrella ('a')

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

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

Output:
      in the default locale, iswgraph(0x2602) = false
      in Unicode locale, iswgraph(0x2602) = true
