Ewww. ;) First, you need the /s modifier on the regex. Second, you need
the /g modifier on the regex. Third, you don't need the () in the regex.
@chars = $str =~ /./gs;
Fourth, split() is far nicer to look at.
@chars = split //, $str;
Fifth, just join() the elements you want.
$str = join '', @chars[0 .. 4095];
Sixth, get rid of the array.
$str = join '', (split //, $str)[0 .. 4095];
But we're not using this approach anyway, are we? ;)
