int main()
{
    wchar_t c = L'\u2602'; // the Unicode character Umbrella ('☂')
 
    std::cout << std::hex << std::showbase << std::boolalpha;
    std::cout << "in the default locale, iswgraph(" << (std::wint_t)c << ") = "
              << (bool)std::iswgraph(c) << '\n';
    std::setlocale(LC_ALL, "en_US.utf8");
    std::cout << "in Unicode locale, iswgraph(" << (std::wint_t)c << ") = "
              << (bool)std::iswgraph(c) << '\n';
}

Output:

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