no, I hope I wrote this is supposed to read the UTF-8 encoded octet,
check if it is a valid UTF-8 encoded string and turn the UTF8 flag ON.

if you want to turn it OFF for a UTF-8 encoded string, you simply use

$str = encode('utf8', $str);

It takes the input string with UTF-8 flag on and "encodes" it into a
UTF-8 octet, which effectively means that it only takes the UTF-8
flag out.

I think the names encode and decode are little bit confusing, until
one gets used to them. Think of it in this way: Perl 5.8 is a stranger
who pretends only to understand UTF-8 encoded (and UTF-8 flagged)
strings. So this Perl guy has to "decode" strings that are not flagged
to understand them as unicode; he can "encode" UTF-8 flagged strings
to any other encoding dialect for the outer world.
