Hi, IIUC, "Symbols and Pictographs Extended-A"[1][2] is a new Unicode block that showed up in version 12.0 and extends the "Supplemental Symbols and Pictographs" block. Since we use Symbola for the latter, I figure it wouldn't hurt to also use this font for the former? AFAICT Symbola covers the whole block[3]. Here is a patch to that effect:
0001-Use-Symbola-to-cover-Symbols-and-Pictographs-Extende.patch
Description: Text Data
(Will followup with an updated patch as soon as I get a bug number.)
FWIW, I found out about this block after
- hearing that Unicode 13.0 included new emojis,
- waiting for an updated version of Symbola to be released[4],
- trying to insert some of the new emojis in Emacs,
- noticing that some of them (e.g. 🩴 U+1FA74, 🪗 U+1FA97, 🫕 U+1FAD5)
are not displayed (C-u C-x = says "display: no font available",
despite Symbola covering them).
- going straight to fontset.el to understand why Symbola wasn't picked
automatically.
Of course, users can work around this with:
(set-fontset-font t '(#x1FA70 . #x1FAFF) "Symbola" nil 'append)
Thank you for your time.
