I would say this is not possible. Netulex always reads characters in
advance (to improve performance). There is a set_encoding function, but
it only affects the next refill (after all read characters are scanned),
but it is almost impossible to control when this happens.

As the read-ahead buffer was the main motivation to write Netulex, my
advice is to stick to plain Ulex. Buffers and encoding changes are hard
to get right at the same time.
