Yes. Looking at the code decode_utf8 has "return $_ if is_utf8($_)" as
it's first line which decode does not.
decode_utf8 also lacks the a check that find_encoding('utf8') succeeded
before using it however if that causes a problem it's because there are
far bigger problems. Another difference is that decode_utf8 appends ''
if $_ is a reference while decode() appends '' without any condition.
