[quote author="Hairul Azami" date="1305114350"]What do you mean save controller file with UTF-8?[/quote]
Before you implementing any Multibyte String function on that article, you must ensure that your controller file (or any related file) is saved with "UTF-8" instead "ANSI" encoding. If you are using Notepad as your editor, look at 'Encoding' option (its default to ANSI) at the bottom of save dialog, if you are using Vim :wq ++enc=utf-8
