Okay for the middle dot. But this (as the changed subject shows) is
about a different character.

I'm fine with that if there's a good reason for it. And I'm sure that
for those that we currently have, there is a good reason.
I still don't see why we need contextual rules for the IDEOGRAPHIC
ITERATION MARK (U+3005). But maybe that's just because I'm too used to
it because I read and write Japanese. For me, it sounds about the same
as if we would say that we have to create some context rules for 'ü' (or
so).
Regards, Martin.
