#include <iostream>
#include <locale>
int main()
{
    const wchar_t c = L'\u2a0c'; // quadruple integral
 
    std::locale loc1("C");
    std::cout << "isgraph('⨌', C locale) returned "
               << std::boolalpha << std::isgraph(c, loc1) << '\n';
 
    std::locale loc2("en_US.UTF-8");
    std::cout << "isgraph('⨌', Unicode locale) returned "
              << std::boolalpha << std::isgraph(c, loc2) << '\n';
}

Output:

isgraph('⨌', C locale) returned false
isgraph('⨌', Unicode locale) returned true
