    long double mon = 123.45; // or std::string mon = "123.45";
    std::cout.imbue(std::locale("en_US.utf8"));
    std::cout << std::showbase
              << "en_US: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
    std::cout.imbue(std::locale("ru_RU.utf8"));
    std::cout << "ru_RU: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
    std::cout.imbue(std::locale("ja_JP.utf8"));
    std::cout << "ja_JP: " << std::put_money(mon) << " or " << std::put_money(mon, true) << '\n';
