Korean characters are not displaying properly in PHP

I have a set of values which are actually korean characters but showing as "uacbduae30ub3c4 ubd80ucc9cuc2dc ubd80ucc9cub85c96ubc88uae38 10 (uc6d0ubbf8ub3d9, ub9c8ub8e8uce90uc2ac)".

I need to convert these value to korean characters.

I tried:

$txt = "uacbduae30ub3c4 ubd80ucc9cuc2dc ubd80ucc9cub85c96ubc88uae38 10 (uc6d0ubbf8ub3d9, ub9c8ub8e8uce90uc2ac)";
$dd = mb_convert_encoding($txt, "UTF-8", "EUC-KR");

But not working.
