std::iswgraph is an STL function to check if a wchar_t is a printable character other than a space.


#include <cwctype>

#include <iostream>



int main()

{

  for (wchar_t i = 0; i!=256; ++i)

  {

    if (std::iswgraph(i))

    {

      std::wcout << i;

    }

  }

}

Screen output:


!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
