It seems save to allow names that pass
bidi-find-overridden-directionality ...  but is there an off-by-one
error there?

It says that this is OK:

           "Lars Ingebrigtsen\N{LEFT-TO-RIGHT OVERRIDE}"

But this isn't:

           "Lars Ingebrigtsen\N{LEFT-TO-RIGHT OVERRIDE}f"

And both are equally suspicious.
