Created attachment 884416 [details, diff] Patch for signal-desktop-bin to depend on a new enough emoji font, allowing correct emoji display, when its emoji USE flag is set I've been experiencing a lot of weirdness and breakage using emoji in recent signal-desktop-bin versions, at least current 6.46.0. Since https://signal.org/download/# only offers debian packages, I'm reporting here first, as their issue tracker requires. (And it is a distribution issue of sorts, as it turns out, see below.) I'd happily like to cross-test against a different / more 'common' build of Signal; but I can't find an AppImage or tarball. Beside the debian package, there seem to be (only, mostly) a flatpak and a snap available. All of which would require further 'infrastructure' on my gentoo install to even try - and I have zero experience what to expect. Which of those packages would it make sense for me to cross-test against, if any? Anyway, the weirdness starts with the emoji picker: https://postimg.cc/PNC4PJHr Most, but not all, emoji are missing / displayed as a broken image icon. From there, it still gets weirder. I'll be using the following test message all throughout: "Moin" :yawning_face: :coffee: "Moin" 🥱☕ And I'll copy each text segment and put it when run through 'od -c' under each image. I can still 'use' those when composing a message, either using Signal's :emoji-name: syntax: https://postimg.cc/XG4JGQp6 "Moin" 🥱 ☕ 0000000 " M o i n " 360 237 245 261 342 230 225 0000020 \n 0000021 or my IBus-based system-wide emoji picker, where the preview message renders as expected: https://postimg.cc/gr1CgrHn "Moin" 🥱☕ 0000000 " M o i n " 360 237 245 261 342 230 225 \n 0000017 When sending those messages, they are displayed back with a broken image symbol preceding each indivdual emoji: https://postimg.cc/LJ83f3gf "Moin" 🥱 ☕ [colon syntax] 0000000 " M o i n " 360 237 245 261 342 230 225 0000020 [ c o l o n s y n t a x ] "Moin" 🥱☕ [IBus system emoji picker] 0000040 \n " M o i n " 360 237 245 261 342 230 225 0000060 [ I B u s s y s t e m e m 0000100 o j i p i c k e r ] \n 0000114 (I've annotated the messages so I could easily identify them; the additional space in the upper message is inserted automatically by Signal when using the :emoji-name: input syntax.) Both those messages show up as expected/without those broken image symbols in a mobile client: https://postimg.cc/p9N7BSf4 On a hunch, I tried unmasking media-fonts/noto-emoji-20231130 which is ~amd64. I had the stable version 20220912-r2 installed before, i.e. that's what the bugs described above are tested against. With this newer font installed, all those issues are resolved. I'm attaching a patch for net-im/signal-desktop-bin-6.46.0.ebuild to require the newer version of media-fonts/noto-emoji-20231130 specifically. On second thought, this is a less ideal situation than I had hoped - I was under the impression that signal-desktop-bin itself is ~amd64, but it's stable amd64 now. For that reason I've put that versioned dependency behind a (new) emoji USE flag on signal-desktop-bin in the patch. What is holding back stabilization of newer media-fonts/noto-emoji? It does seem to present as a necessary change to existing functionality, not just missing a few new exotic glyphs, after all. (In some sense, it's 'not just' the emoji/font rendering pipeline - I'm also using telegram-desktop (which is also electron-based), where emoji are not broken against the stable noto-emoji fonts package. ...)
Id wager best course of action is to open a stabilisation bug for noto-emoji and bump the requirement in a new revision. Use flags for higher requirement isn't a thing that ::gentoo does. CC'ing pacho as he may be interested as the maintainer of noto-emoji in breakage like this.
Stabilization requested in bug #923973
