In order to simplify emoji processing, these should be stored in the 
data stream in logical order.  Whether these cool new characters become 
reordrant color blobs or not would depend upon language.  So, what we'd 
need is some way of indicating language in plain-text. Some kind of 
tagging mechanism.

FAICT, the emoji repertoire is vendor-driven, just as the pre-Unicode 
emoji sets were vendor driven.  Pre-Unicode, if a vendor came up with 
cool ideas for new emoji they added new characters to the PUA.  Now that 
emoji are standardized, when vendors come up with new ideas they put 
them in the emoji ranges in order to preserve the standardization factor 
and ensure interoperability.  (That's probably over-simplified and there 
are bound to be other factors involved.)

We should no more expect the conventional Unicode character encoding 
model to apply to emoji than we should expect the old-fashioned text 
ranges to become vendor-driven.
