emacs/admin, branch scratch/bug-44858 Emacs is the extensible, customizable, self-documenting real-time display editor. Generate skin tone compositions from emoji-sequences.txt 2021-09-24T11:10:48+00:00 Robert Pluim 2021-09-23T09:31:46+00:00 6738111ae2baa45f1eb53e0d208f49855af128d6 Read skin tone modifier sequences from emoji-sequences.txt and add them to the per-character composition rules derived from emoji-zwj-sequences.txt, rather than adding them as lookback rules for the skin tone modifiers. This avoids an issue with the application of such lookback rules. See Bug#39799, specifically <https://lists.gnu.org/archive/html/bug-gnu-emacs/2021-09/msg01878.html> for more details. * admin/unidata/Makefile.in (zwj): Add emoji-sequences.txt as a dependency. * admin/unidata/emoji-zwj.awk: Match RGI_Emoji_ZWJ_Sequence and RGI_Emoji_Modifier_Sequence. Remove manual addition of skin tone composition rules with lookback.
