Sorry for the vague subject, but I have no idea how to describe what's 
happening here:

         =====
use feature 'unicode_strings';

my $x = "\x{263a}";
$x =~ /$x/;

my $text = "Perl";
die if $text !~ /P.*$/i;
         =====

The program does nothing (as expected) in perl 5.14.2, but dies in perl 
5.16.2.

Is it a known issue, or should I file a bug report?


Thanks,
Anders.
