I've gotten about half of this - part of it is a sign-extension bug (which
creates the odd characters), but after that, it seems that there's some
additional problem, which causes the UTF-8 to be inserted in the wrong order.

I'll continue to investigate.

However - just checking - on FreeBSD, you're using a port (I assume),
so my fixes probably won't be visible til a release (is that right?).
