On this particular point I feel you disagree with my computer?

This is what we all think. In this case we have someone who proposes a
change in some _non-DNS_ rules. I want to make sure that we agree on the
implications of what he proposes. The first step is my question.

Then I want to know how his proposed change may or not modify the context of
my own solution to my own need, i.e. when ecole.fra and Ecole.fra entered by
the user are not intended to be equivalent. The second step of my question.

There is no step related to the DNS.

But, for the basic functionality and distinctions, top asking: you are about

No. I only have a problem to solve of inconsistency between French, Unicode,
Hosts.txt, DNS and IDNA. There are several possible solutions. The simplest
ones seems to depend on the consideration of Adam Costello's mail. Wil does
that. But I feel he does it only partly.

Over all, I certainly prefer your solution that Wil's young positions, but
you proposed it later on. And I did not have time to check how it compares
with Adam's canonalization.
