Use set_charset to turn current charset to utf8, and you will be able to display Asian fonts.
$db_link = mysqli_connect($db['host'],$db['user'],$db['pass'],$db['db']);
// echo "Initial character set is: " . $db_link -> character_set_name();
$db_link -> set_charset("utf8"); // Change character set to utf8
// echo "Current character set is: " . $db_link -> character_set_name();
