I did test this with Japanese characters which had double-width, and
recall that moving the cursor within the edited text was working properly.
That should have been enough to verify this aspect - either I'm missing
something, or your curses+iconv+terminal configuration isn't doing it

I got the examples).

Beyond that - the key-binding part of the code probably requires some
further work.
