This covers both sequences using Zero-Width-Joiner codepoints and those without. Bug#39799, I hope. * .gitignore: Add emoji-zwj.el * admin/notes/unicode: Add emoji-zwj-sequences.txt and emoji-sequences.txt references. Describe how to test after updating to a newer Unicode version. * admin/unidata/Makefile.in (all): add emoji-zwj.el as a dependency. (emoji-zwj.el): Add target plus rules for building. (gen-clean): Add emoji-zwj.el. * admin/unidata/README: Add emoji-zwj-sequences.txt and emoji-sequences.txt references. * admin/unidata/blocks.awk: Force emoji script to be used for certain codepoints that are used by the Unicode sequences. * admin/unidata/emoji-sequences.txt: New file. * admin/unidata/emoji-zwj-sequences.txt: New file. * admin/unidata/emoji-zwj.awk: New file. Derives composition-function-table rules from emoji-zwj-sequences.txt, plus hardcodes some derived manually from emoji-sequences.txt. * etc/NEWS: Announce change. * lisp/international/characters.el: Load the generated emoji-zwj.el * src/Makefile.in (emoji-zwj): New target. (temacs): Add emoji-zwj as a dependency.
