L2/04-419

From: Mark Davis
Subject: ArabicShaping suggestion
Date: Thu, 18 Nov 2004 08:20:54 -0800

I have not seen any consensus on this list for any changes to shaping,
beyond the one action already given by the UTC:

[100-A36] See if there are any Arabic shaping differences between
canonically equivalent sequences; if so, propose remedies and post to bidi
list (see item 2 of document L2/04-290).

It is clear that we need to make sure that the canonical equivalents shape
the same. Below is my verification of the item raised on this list. (The
decomposition of each character is listed with ***.) The only conflict is
with

Right_Joining 06C2 ARABIC LETTER HEH GOAL WITH HAMZA ABOVE
*** Dual_Joining 06C1 ARABIC LETTER HEH GOAL
***CONFLICT***
*** Transparent 0654 ARABIC HAMZA ABOVE

The suggestions from everyone so far are to resolve this by changing 06C2
ARABIC LETTER HEH GOAL WITH HAMZA ABOVE to be Dual_Joining. I will recommend
that to the committee for the meeting today (the last day of the meeting).
This will go into the beta, so if people come up with a different consensus
on the change, we will have time to change it in the very next meeting
(Feb), the last before Unicode 4.1 comes out.
