OK. Whilst updating the emoji sequences support to Unicode-14, I had to add the following ranges to the 'emoji' script, since otherwise they don=CA=BCt end up getting composed, because Emacs doesn=CA=BCt use the 'emoji' font for them. They=CA=BCre all Emoji_Presentation=3DNo, but emoji-zwj-sequences.txt modifies them with FE0F (why didn=CA=BCt they just change them to Emoji_Presentation=3DYes? I see very little consistency between similar codepoints that nonetheless have different Emoji_Presentation values) (#x26F9 #x26F9 emoji) (#x2764 #x2764 emoji) (#x1f3cb #x1f3cc emoji) (#x1f3f3 #x1f3f4 emoji) (#x1f441 #x1f441 emoji) (#x1f575 #x1f575 emoji) So we get to pick our poison: complete consistency with the Emoji_Presentation property from emoji-data.txt, or having complete coverage for emoji-zwj-sequences.txt. Eli? (I=CA=BCll admit to having a slight preference for the latter, given that I find Emoji_Presentation to be somewhat arbitrary for quite a few codepoints) Robert --=20
