        Was curious whether the Zero Width Joiner was ad-hoc with anything
        provided, or a long list of specific combinations.  Turned out it was
        specific combinations, and the list is rather impressive. [1] 
        
        Unicode.org has a list of the recommendations [1].  It's somewhat long.
         Takes a bit to load.  There's also a bunch that are "really" long. 
        "man facepalming: medium-light skin tone" is great.  U+1F926 U+1F3FC
        U+200D U+2642 U+FE0F  Now I can do a Picard in Unicode.  Now if only
        they had "man who is bald facepalming."  Pretty sure that means adding
        U+1F9B2 somewhere, maybe U+1F468 U+200D U+1F9B2.
        
        U+1F468 U+200D U+1F9B2 U+1F926 U+1F3FC U+200D U+2642 U+FE0F kind of
        works.
        
        Also like U+1F9B9 U+200D U+2642 U+FE0F, "man who is supervillain". 
        Current version looks more like Minions movie, and suggested sample
        looks more like "mime vampire who is stuck in plastic action figure
        container"

          Unfortunately most of the benefit of this was undone by Apple's
          rollback of their family emoji rendering to just be shapes :/. Cool
          UX though!

        Is there any specification on how "far" a zero-width joiner can reach?
        I thought a ZWJ would only affect the codepoints directly adjacent to
        it, but here we have sequence of 5 codepoints and only one ZWJ for all
        of them (which is also the only codepoint that signals that "special
        treatment" should be applied here).
        
        So how would a parser know all five codepoints make up a grapheme
        cluster and not just the inner three?
        
        Edit: Ok, didn't realize the "Fitzpatrick" codepoints are modifiers
        that I guess always refer to the previous codepoint. So there is
        essentially an "operator precedence" defined between modifiers and
        ZWJs.
