Re: [charmod-norm] Does ZWJ/ZWNJ affect meaning?

In addition to the language-related issues noted, some other interesting examples have shown up in the context of various proposals to allow emoji in IDNs and elsewhere.  The Unicode emojii description, at least as I read it, restricts the use of ZWJ with emoji.  However it seems likely, given the very nature of emoji, that creativity will prevail over those restrictions (illustrated by a recent XKCD piece).  Since there are no applicable normalization  rules, even for ordering within a combining sequence, and that it is unclear whether, for a given emoji code point E, E ZWJ E is equivalent to E, adds emphasis, or describes/ illustrates something else entirely (lurid examples on request), the area is fraught with "opportunities" for confusion and positive and negative mismatches.
