    Fix Description: The charset conversion was not working, which caused the
    message about the charset is not supported.  The size of the conversion
    buffer was negative, and this caused the conversion to utf8 to fail.  This
    caused, among other things, the problem with the authentication credentials.
    Platforms tested: RHEL6 x86_64, Fedora 20
