int main()

    const std::locale empty_locale = std::locale::empty();
    typedef std::codecvt_utf8<wchar_t> converter_type;  //std::codecvt_utf16
    const converter_type* converter = new converter_type;
    const std::locale utf8_locale = std::locale(empty_locale, converter);

    std::wifstream fin("Test_GetNextChar.txt");  //input
    fin.imbue(utf8_locale);

    wchar_t ch;
    while (!fin.eof())
    {
        fin >> ch;
        std::cout << ch << std::endl;
    }
