$string = decode(ENCODING, $octets [, CHECK])
         Decodes a sequence of octets assumed to be in ENCODING
         into Perl's internal form and returns the resulting
         string.  As in encode(), ENCODING can be either a canon-
         ical name or an alias. For encoding names and aliases,
         see "Defining Aliases".  For CHECK, see "Handling Mal-
         formed Data".
