How to know if string is UTF-8 encoded?

803959Jan 17 2011 — edited Jan 18 2011
Hello All,

I have an instance in my application. Where I need to get one parameter from URL. There is possibility that whatever I get as string can be encoded or can be not encoded.

And if its encoded I have to decode it before using.

Can anybody please suggest me the way by which we can identify if particular string is already UTF-8 encoded or not?

Thanks,
Jenish
