what character encoding is c3 82 c2 bf?
===

I have a source of text data that includes the byte sequence c3 82 c2 bf. In context I think it's supposed to be a capital Greek Phi symbol (&Phi;).

Anyway I can't figure out what encoding is being used; I'm writing a Python script to process this data into a database that expects Unicode, and it throws an exception on this particular sequence of data.

Any suggestions on how to handle it?
