Even with a source code encoding, you will probably have problems with
source files including \xe2 and other "bad" chars. Unless they happen to
fall inside a quoted string literal, I would expect to get a SyntaxError.

I have come across this myself. While I haven't really investigated in great
detail, it appears to happen when copying and pasting code from a document
(usually HTML) which uses non-breaking spaces instead of \x20 space
characters. All it takes is just one to screw things up.
