Fwd: [Unicode Announcement] New Public Review Issue #147: Proposed Depre

As the liaison from IETF to the Unicode Consortium, I would like to  
make the IETF community aware of the following opening for public  
comments.
The character U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW that the  
review is related to has today the derived property value "PVALID" in  
the current proposal discussed in the IDNABIS working group.
Because of this, I encourage interested parties to respond to the  
questions stated below.
I am confident IETF and Unicode Consortium will be able to synchronize  
the two standards so that there is no incompatibility issues.

> PRI #147: Proposed Deprecation of U+0673 ARABIC LETTER ALEF WITH WAVY
> HAMZA BELOW
>
> The UTC has recently approved a proposal to encode an ARABIC WAVY  
> HAMZA
> BELOW for a future version of the Unicode Standard. That character is
> used productively in Kashmiri and other languages, and is applied to
> letters other than ALEF. The intent is to deprecate the existing
> character U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW, in favor of
> the sequence of an ALEF plus the new ARABIC WAVY HAMZA BELOW. (Because
> of normalization stability constraints, a canonical equivalence  
> relation
> cannot be established.)
>
> The UTC is seeking feedback on whether U+0673 should be deprecated  
> when
> ARABIC WAVY HAMZA BELOW is encoded. Pertinent information would  
> include
> data on how widespread usage of this character is. Note that  
> deprecation
> of a character does not mean removal of that character from the
> standard; it merely constitutes a strong recommendation not to use the
> character.
