I send you this node in order to have your advi...nevermind.

Is there an efficient way to get a strings byte length instead of character length? The two solutions I came up with myself are rather slow and rely on non-utf8 string weirdness in Perl 5.6.

# Prototyped ($), just like length. Please do not bitch about that.

sub byte_length ($) {
    my ($copy) = @_;
    my $counter;
    $counter++ while $copy =~ s/.//s;
    return $counter;
}

sub byte_length ($) {
    return scalar split //, $_[0];
}

Other versions of byte_length are appreciated, 'cause I don't like abusing bugs. (Especially when it's already fixed in a new version :)
