I'm not sure I quite understand what you're saying.  The first time a
non-ASCII byte is encountered, the code will 'fire' and apply the
heuristic to set an encoding.  Once the encoding is set, the code won't
be called again.

The perlpodspec seems pretty clear that a POD document containing
different encodings should be considered an error.
