      I do like how a lot of "this capture group is not a backreference" and "match zero to one of these" make a regex look really confused. ?????

      Let's add the sequences now. Combining Enclosing Keycaps: [0-9#*]\ufe0f?\u20E3 (Some vendors use VS-16, some don't).

      Skin tones are harder, as their applicability is very fluid. (?:[\uD800-\uDBFF][\uDC00-\uDFFF]|[\u261D-\uFFFF])\uFE0F?\uD83C[\uDFFB-\uDFFF]

      This is roughly what I ended up with. This potentially finds ZWJ and sequences, but will give false positives without current Emoji data.pic.twitter.com/hEOAHm3Wfo

      This is ultimately futile and as 3166-2 subregions emoji show us, subject to gross changes in emoji sequence definitions in the future.

      As @ManishEarth points out, TR29 gives you very helpful information http://unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries … (that is useless without staying updated).

      "Rely on 3rd-party framework/library to stay updated, for rest of your project's life" should not be only answer to "How can I easily do X?"

          People want emoji fast. And browsers still take about a year to update to the latest Unicode data files internally. Quick and Dirty tester: (v=>{x=[...'ɹༀඅऄॻॳॸૹಀৼՠ౷'];for(i in x){a=document.createElement('a');a.href='http://'+x[i]+'.ws';if(/(%|zn7c)/.test(a.href))return i}})()

          (No, we don't have a better solution (other than to remove emoji from Unicode before they end up in the Stability Policy). We just like to complain....)
