It's probably UCS-2, what Windows often calls UTF-16. Even if it's not, it's a convenient way of avoiding the problem. 
use strict;
use warnings;

use Encode qw( decode );

my $s = '';
$s .= pack('v', $_) for 0..65535;

for my $enc (qw( UCS-2le UTF-16le )) {
   printf( "%-9s %s\n",
      "$enc:",
      eval { decode($enc, $s); 'success' } || 'error'
   );
}
