Point taken.

But I'm not sure that what you say is true of "any other pairs",
where pair is regarded as two chars that we might consider using
as code/key phrase bookends.

I'm thinking of the pair ` and ', for instance.  Not exact mirror
images by any means, but workable.  The point is that there might
well be such pairs that are not problematic for Bidi - chars that
we humans might consider as pairable enough for our purposes.

Anyway, I'm not looking for a different pair from `...'.  If
someone finds one that satisfies the criteria, I'm open to it, of
