Thanks for that. THe Yes sufficed, but I 
appreciate that you ran a tool on the data.

Between now and Friday? Unlikely.

That's Friday.

You ought to. It is in YOUR interests and in the 
interests of YOUR constituents to do so. And I 
say this as Irish NB representative to WG2, who 
am often at loggerheads with the UTC. So my 
opinion is not a Unicode opinion. (Though I 
suspect they hold the same view. You OUGHT to 
follow these processes carefully.)
