you shouldn't normally need to test for the new style as it is more of
less the same as

so in a new or old format utf8 processing is in effect  if this says UTF-8

\ifx\xxx\inputencodingname  UTF-8\else not\fi

similarly in an old or new format either inputencoding has not been
used, or it has been backed out with \UseInputEncodeing if this says

\ifx\undefined\inputencodingname  RAW\else not\fi
