--- Comment #1 from Adam D. Ruppe <destructionator at gmail.com> ---
Whatever happened to that dip 1008 thing?

Or perhaps we could just change the invalid utf 8 sequence exception to the
replacement char. I'd personally argue that is more useful for writing anyway
(I often cast stuff to byte for it)
