I am no expert on this issue, but I do edit languages such as French
and Spanish which use non-ASCII characters.  It seems to work fine.  I
never insert zero-width characters, at least not knowingly.  Would
they be inserted without my knowing?

If not, I think that some non-ASCII text works fine.

Emoji show up on my terminal as diamonds, since it can't display them.
So do the ligatures.  Ideally we could display the ligatures as two
letters.

It would be very nice to do better,  What would we do?

Perhaps we should convert ligatures on file input-in into digraphs,
and convert digraphs on file output into ligatures when using some
coding system.
