Visual Studio Code – Is there a way I can configure VS Code or Code::Blocks so that the terminal can output Russian characters?

auto utf16_to_utf8 = [](const std::wstring &value) -> std::string {
    int len = WideCharToMultiByte(CP_UTF8, 0, value.c_str(), -1, NULL, 0, 0, 0);
    if (len)
    {
        std::string utf8 = std::string(len, '');
        WideCharToMultiByte(CP_UTF8, 0, value.c_str(), -1, &utf8[0], len, 0, 0);
        return utf8;
    }
    return std::string();
};

auto utf8_to_utf16 = [](const std::string &value) -> std::wstring {
    int len = MultiByteToWideChar(CP_UTF8, 0, value.c_str(), -1, NULL, 0, 0, 0);
    if (len)
    {
        std::wstring utf16 = std::wstring(len, '');
        MultiByteToWideChar(CP_UTF8, 0, value.c_str(), -1, &utf16[0], len, 0, 0);
        return utf16;
    }
    return std::string();
};

Then do: std::wcout<<utf8_to_utf16(u8"Приветn");
Windows terminals have been notoriously bad with displaying UTF-8, until recently in Windows 10 or 11. So you’d be better off outputting UTF-16.
