$input = '\\xd0\\xa0\\xd1\\x83\\xd1\\x81\\xd1\\x81\\xd0\\xba\\xd0\\xb8\\xd0\\xb9';
$input2 = "\xd0\xa0\xd1\x83\xd1\x81\xd1\x81\xd0\xba\xd0\xb8\xd0\xb9";
$output = preg_replace_callback(
  '/\\\\x([a-f0-9]{2})/',
  function($match) {
    return pack('H*', $match[1]);
  },
  $input
);

var_dump($output, $input2 === $output);
