Determining the language of the text

[ron barber]

Hi again,

This is an attempt to get at my problem a different way. Is there a way 
to tell what language a given chunk of text is?

If I ask for user input, it may be in english or japanese or korean for 
example. If I need to unidecode the text, I need to know if it is 
japanese or korean. If it is english, I may not even need to unidecode 
for my purposes.

So, is there a way to tell what language a given chunk is in?

Thanks,
Ron
