Tags and emoji

[William_J_G Overington]

Unicode regularly encodes some emoji, each with its own code point.
Yet, as there is a quota each year, some acceptable requested emoji do 
not become encoded at all.
--
Tag sequences are used for the flags of England, Wales, and Scotland.
--
The QID Emoji proposal, which was not accepted, possibly because it 
would have meant some emoji being given Unicode status without prior 
oversight by the Unicode Technical Committee, nevertheless did include a 
good encoding format that applied tag digit characters.
--
So I write to seek opinions please on whether it would be a good idea 
that that tag format could be applied so as to uniquely encode all those 
acceptable emoji that have been formally proposed to Unicode Inc. yet 
have not been selected for the annual quota.
The emoji thus encoded might not become implemented by mainstream 
platform businesses yet there could be good opportunities for 
independent artists and fontmakers and would go some way to bringing a 
good result to the proposers of otherwise unencoded emoji proposals. If 
there were a practice that fonts supporting in whole or in part such 
emoji had visible glyphs for the tag digit characters, an unsupported 
tag emoji would be indicated by the displayed digit sequence.
This would be a far better solution than using a Private Use Area 
encoding.
