My concern with this approach is that it will break pretty much all current Arabic fonts.
In instances in which the chairless hamza becomes 'transparent', i.e. when the letters on
either side of it join, there needs to be an appropriate glyph substitution and
positioning rules applied. Since most Arabic fonts currently treat the U+0621 as dividing,
they will be unable to handle such situations if the character suddenly is given new
properties. This is a particularly nasty situation for both font developers and users,
since different software will implement the change at in different development cycles,
users will adopt the new software at varying rates, there will be continued demand for
fonts that work the old way, etc. A real mess.
So if the issue is not to be addressed solely at the display level -- with perhaps an
explanatory note added to the text of the Unicode Standard --, Khaled's suggestion is the
cleanest way to implement a character-level solution.
