I don't follow the argument.  Since some users actually use zero-width
characters, that seems to give us two choices (at least):

* Leave zero-width characters unflagged by default.

* Flag zero-width characters by default, and those users can
turn that off.

I don't know which is better -- I think it depends partly on what
fraction of all users find the zero-width characters useful.

That sounds good.
