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

NAME
       std::iswprint - std::iswprint

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

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

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

Example
       // Run this code

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

	int main()
	{
	    wchar_t c =	L'\u2002'; // en-space
	    std::setlocale(LC_ALL, "en_US.utf8");
	    std::cout << std::boolalpha	<< std::hex << std::showbase
		      << "in Unicode locale,\n"
		      << "iswprint('" << c << "') = "
		      << (bool)std::iswprint(c)	<< '\n';

	    c =	L'\u0082'; // break permitted
	    std::cout << "iswprint('" << c << "') = "
		      << (bool)std::iswprint(c)	<< '\n';
	}

Output:
	in Unicode locale,
	iswprint('0x2002') = true
	iswprint('0x82') = false
