Multiple languages in Tinymce

Hi All,

I want to know how to add language pack in tinymce. Like there should be a dropdown in tinymce to select languages , if i select a language ex. Chinese then i should be able to type in Chinese (font) in tinymce. Can anyone give me an idea how to work on this ?

I have also posted the same question in tinymce forum and i got this reply.
Tinymc

I was able to do this in Joomla(with Tinymce editor) for Indian languages. I have attached a screen shot.
