Wow - I see that I hadn't carefully looked at the wikipedia page I linked to.

 https://en.wikipedia.org/wiki/Emoji

It seems that the popularity of "texting" has led to a redefinition in many influential quarters of what text is.  I'm now thinking that at least some emoji are downright evil (from a font perspective) - in color and animated!  That makes this thread even more esoteric than I thought, though perhaps still of interest to documentation folks, who are perhaps more interested in fonts and characters than most.

Some more information is here, about how on Macs, colored emoji even show up in the Terminal app, even though it still seems that Unicode does not specify what color a character can show up in.

 Color in the Unicode standard? - Stack Overflow

Quoting from a Unicode FAQ:

 http://unicode.org/faq/emoji_dingbats.html

 Some of the characters from the core emoji sets have names that include a color term, for example, BLUE HEART or ORANGE BOOK. These color terms in the names do not imply any requirement about how a character must be presented; they are intended only to help identify the corresponding character in the core emoji sets.

What do apps need to do to get color emoji via FreeType/HarfBuzz?

Does Ubuntu support animated emoji anywhere?

I see I've been missing the debate for a while.  E.g. from 2011:

 Please Don't Use Emoji - Kirsle.net
  https://www.kirsle.net/blog/entry/please-don-t-use-emoji

Is this as bad as I'm thinking for interoperability in general, for lots more than Ubuntu documentation?

Sigh,
