To the degree that these two sequenced have a relationship, this is the
kind of relationship where users may (I write may) expect the system to
treat *non*-identical entities as if they were the same, essentially,
such desire would be a question of desire for a "fuzzy" match. And
that's not native to the DNS (despite attempts to bring this in via the
back door by allocating multiple labels to the same requester). Agree
with John, it's a different discussion.

Typical case of "accidental confusibility".

This is where I think it intersects with our current discussion.
When two sequences are ruled non-identical it has consequences for
keyboard layouts; they are usually not both present.
In fact, in the vast majority, one of the sequences (usually the one
that is not a singleton) is encoded for some specialized use (or
potential use) and the other one (usually the singleton) is the one that
is encoded for support of an orthography and can be expected to be
(widely) available on keyboards.
So, we we agree that the question of whether things are on the same
keyboard is relevant, then it is relevant to this discussion.
