Personally, I think ass-u-ming Unicode is encoded as UTF-8 would have
been sane, but I can understand that not everyone agrees; e.g. Java
wants UCS-16 if I remember correctly. And not serializing to UTF-8
by default catches errors that would otherwise cause mysterious things
to happen.

Maybe add a transport wrapper class that has

    def write(self, data):
        if isinstance(data, unicode):
            data = self.serializeUnicode(data)
        self.wrapped.write(data)

of course, that means the Protocol receiving this needs to convert from
the used serialization format to Unicode.
