Re: [precis] local case mapping

[Andrew Sullivan <[e-mail]>]

Dear colleagues,

I reviewed draft-ietf-precis-mappings-03 today, at long last.  I
apologise for being so late.

I put together a number of incoherent questions about the case folding
stuff, but fortunately I re-read the mailing list archives on this
topic before posting a long message.  I agree with Peter: I find this
section of the document very confusing, and I think it may be wrong.
In particular …

…I am pretty sure it shouldn't be left the way it is.

It seems to me that our principle generally needs to be that Unicode
is the thing we use, and if Unicode is broken it's Not Our Problem.
So we should figure out how to say, "Do the Unicode-y right thing
here," and then put that in.  I especially don't want to get into
specifying special language-specific tables ourselves: we don't have
the expertise, I think.

I can't think of any better suggested text than what Peter already
sent, so I think that's the right direction.  In the unlikely event
something clearer comes to me in the night, I promise to write it
down.

Best,

A
