It seems that decode_utf8(...) is a no-op if the input string has the UTF8 flag on, but decode("utf8", ...) will always try to decode regardless of the state of the UTF8 flag.But the documentation says that they are equivalent. So the documentation would appear to be at odds with the behaviour.
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.
