Right, I see the problem now.

Why not use `(decode-coding-string "\xc2\xa9" 'utf-8)' right away?  It
gives me the right character directly.

Btw, why don't we have a feature in cc-mode to transparently decode
and encode such strings when the source file is read/written?  If
detecting the encoding is an issue, we could for starters ask that
users state that in some file-local variable.
