Well said.  When the core stuff is done, I'm going to
implement a set of "TypedString" helper routines which
will remember what they are encoded in and won't let
you abuse them by concatenating or otherwise mixing
different encodings.  If you are consciously working
with multi-encoding data, this higher level of
abstraction is really useful.  But I reckon that can
be done in pure Python (just overload '%;, '+' etc.
with some encoding checks).
