Language recognition

[Peter Hickman]

Looking at the public twitter feeds I note that although they are in 
UTF8 they do not indicate the language that they are in. I realise that 
this would be somewhat difficult. But just how difficult?

Given the utf8 entities (is that the correct term) is there an easy way 
to tell which language it might be from, or at least which script?

I'm sure something could be hacked up but rather than some adhoc rules 
it would appear that this could be revered from the Unicode.

Any pointers?
