perldoc utf8
$success = utf8::decode($string)

Attempts to convert in-place the octet sequence in UTF-X to the corresponding character sequence. The UTF-8 flag is turned on only if the source string contains multiple-byte UTF-X characters. If $string is invalid as UTF-X, returns false; otherwise returns true.

Note that this function does not handle arbitrary encodings. Therefore Encode is recommended for the general purposes; see also Encode.
