Since you already know what sequence of encoding and decoding lead to the broken output, the easiest way with Encode::Repair is this:

use 5.010;
use strict;
use warnings;

use Encode::Repair qw(repair_encoding);
my $broken = '敒剕䕇呎';
say repair_encoding($broken, [decode => 'utf-8', encode => 'UTF-16LE']);
__END__
# output:
Re: URGENT

But it also works with learn_recoding:

use 5.010;
use strict;
use warnings;
use Encode::Repair qw(repair_encoding learn_recoding);
binmode STDOUT, ':encoding(UTF-8)';
my $broken = '敒剕䕇呎';

my $pattern = learn_recoding(
    from    => $broken,
    to      => 'Re: URGENT',
    encodings => ['UTF-8', 'UTF-16LE', 'UTF-16BE'],
);

if ($pattern) {
    say repair_encoding($broken, $pattern);
}

So, what did you try?

(Updated to use pre tags instead of code, because code tags badly break most non-ASCII-chars.
