I'm curious how this impacts IDNA2003 compatibility and particularly the proposed IDNA2008 mappings. I suppose it is unlikely that this character is currently registered in a "real" URL?

Subject: Fwd: [Unicode Announcement] New Public Review Issue #147: Proposed Deprecation of U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW
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.
