    Try decoding string to UTF-8 on error message fail

    Database Errors from SQLAlchemy tend to get mangled into ASCII. If an
    error is process that contains UTF-8 data in ASCII form if fails to
    build the message and will lead to a 5xx error. Catch the error and try
    to decode it to create the message again, if that doesn't work at least
    fail gracefully.
