The code below implements the conversion you requested. However, I would still recommend the true UTF-8 solution as recommended by other monks.

use strict;
use warnings;
my %cfg = (
    'default.player',  "\xeb\xa6\xac\xec\x9e\x91",
);
my $name = '\\xeb\\xa6\\xac\\xec\\x9e\\x91';

my $a = $cfg{'default.player'};
my $b =  eval q(") . $name . q(");
if ($a eq $b) {
   print "indahouse\n";
}
