#include <cctype>
#include <clocale>

int main()
{
    char c = '\xd7'; // the character × (multiplication sign) in ISO-8859-1

    std::cout << "ispunct(\'\\xd7\', default C locale) returned "
               << std::boolalpha << (bool)std::ispunct(c) << '\n';

    std::setlocale(LC_ALL, "en_GB.iso88591");
    std::cout << "ispunct(\'\\xd7\', ISO-8859-1 locale) returned "
              << std::boolalpha << (bool)std::ispunct(c) << '\n';
}
