> I figured out this issue, it was due to my custom font configuration in ~/.config/fontconfig/fonts.conf'. When deleting that file, emojis display and I can also set the face- and frame-fonts to emoji fonts. Probably it's just broken, but I think it's still possible that it's formally correct, but the hinting and aliasing rules that it specifies cause some bug down the line. Feel free to close this, though if anyone is interested, I attached the file.

Thank you for telling us. I'm therefore closing this bug.
[Message part 3 (message/rfc822, inline)]
I use emacs under wayland (sway) with PGTK and native compilation,
compiled from master. However, I found that in this configuration, at
least in my recent builds, unicode emoji are not properly displayed.
E.g. if I call `emoji-list', most emoji are not shown at all, except
very basic emoji like "Smileys > affection." If I insert a unicode
emoji, I just see a unicode placeholder. Calling `describe-char' on the
"Smileys > smiling" emoji from the *Emoji* buffer gives gives me:
position: 65 of 2529 (3%), column: 0
character: C-j (displayed as C-j) (codepoint 10, #o12, #xa)
charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x0A
script: latin
syntax: which means: whitespace
to input: type "C-x 8 RET a" or "C-x 8 RET LINE FEED (LF)"
buffer code: #x0A
file code: not encodable by coding system nil
display: no font available
I tried using a different emoji font via customizing the emoji face,
where I set the font family to "JoyPixels", but this resulted in emacs crashing.
I could not find an existing ticket with "emoji" in the subject that
fits my symptoms, but maybe I didn't look properly or this is a symptom
of another known bug. Or I just misconfigured something on my system
which results in problems with the coding system or something that
happens due to my compilation options. Anyway, I don't know what else to
do to fix this on my own, so I would be happy for hints of if this can
be fixed somehow.
Best regards,
Michael Eliachevitch
