In MS Word 2016 on Windows 10, I get an intermediate stage of “Man: Dark Skin ZWJ”, which is comparable to my suggestion that only the consonant be deleted from a sequence of Indic stacker + consonant, even though it be very similar to a unitary consonant sign. The main difference in the Indic pair is that there is a (misplaced) grapheme cluster boundary in the former. Mark Davis has proclaimed that all these emoji behaviours are WRONG. What is wrong is that the ZWJ may go missing with copy and paste, as I found between Word and plain Notepad. Richard.
