Are you sure you saved your file as utf8? When I copy the source and save it, it doesn't contain the byte \xF0 anywhere. The sequence f069 2020 is present, however, when I convert the file to iso-8859-1:

iconv -f utf8 -t l1 1.pl | xxd | grep f069.2020
00000030: 6638 3b0a 0a6d 7920 2476 6569 f069 2020  f8;..my $vei.i
