#include <iostream>
#include <locale>
int main()
    const wchar_t c = L'\u214b'; // upside-down ampersand
    std::locale loc1("C");
    std::cout << "ispunct('⅋', C locale) returned "
               << std::boolalpha << std::ispunct(c, loc1) << '\n';
    std::locale loc2("en_US.UTF-8");
    std::cout << "ispunct('⅋', Unicode locale) returned "
              << std::boolalpha << std::ispunct(c, loc2) << '\n';


isalpha('⅋', C locale) returned false
isalpha('⅋', Unicode locale) returned true
