Well, who thinks Khaled's example
(http://www.amirifont.org/fatiha-colored.html) is a "text presentation"
and who thinks it is an "emoji presentation"? I think it's a text
presentation.

If "text presentations" have to be monochrome, as Asmus claims, I think
the UTC ought to effectively change the emoji property from a binary
property to an enumerated property with values like "monochrome",
"multicolour", and "emoji".  There might be technical problems, but I
suspect the the emoji property is be covered by Unicode stability
guarantees.  The property is in no way part of the Unicode standard.

However, it is probably something best left to a higher order protocol
- as may be done for some emoji.  Individual requests would have to be
justified on a character by character basis.
