Poco Logging with std::wstring or wchar_t

Is it possible to log std::wstring with the Poco Logger?

Like in this short example:

int main(int argc, char** argv)
{
    Logger& logger = Logger::get("Testlogger");
    std::wstring WStringMessage = L"Message as a WString";
    std::string StringMessage = "Message as a String";
    //logger.information(WStringMessage); //Did not compile because it only takes a String
    logger.information(StringMessage);


    system("PAUSE");
    return 0;
}

Is there a possible Solution or did i have to convert every std::wstring to a std::string?

And how is the std::wstring Support in other Poco Libraries like the XML one?

Solution

  • Poco interfaces are utf-8 only, so you will have to convert the string to utf-8 before sending it to the logger:

    std::string msg;
Poco::UnicodeConverter::convert(WStringMessage, msg);
logger.information(msg);

    For XML, see here, but basically the recomendation is the same - use utf-8.
