Detecting language of a string

Hi friends,

Need your help, there is one urgent requirement.

I have to treat a field in two different ways.

If string (content of field) is in English language, then i have to concatenate it in one way.

But if it's in Chinese then i have to concatenate it in another way.

Do we have any function module to detect the language or any SYST field for the same.

Help will be greatly appreciated. Thanks!!!!
