in thread Make a variable safe for a regex.

Is there a way to do this for UTF-8 strings too? \Q will break multi-byte characters.

    Can you supply a test case for that? I've tried (shortly) and it seems to work for me:

    C:\>perl -le "my $str = qq(foo\x{100}bar); my $re = qr/^\Q$str\E/; war
+n $str; warn $re; warn $str =~
 /$re/;"
foo─Çbar at -e line 1.
(?-xism:^foo─Çbar) at -e line 1.
1 at -e line 1.

    Maybe it fails for some other cases of unicode chars, and if so I'd consider that a bug.
