Broken rendering on Debian

[knghtbrd]

On Debian sid, I'm getting this (which will affect the upcoming Debian bookworm stable release):

This after doing literally everything to UNDO the new overriding of Google's soulless, lifeless, emotionless "emoji" and utterly failing until I nuked fonts-noto-color-emoji from orbit.

I have no idea if Noto overriding literally everything is related to #101 or not, but on Linux that's very likely part of the problem. However at least apps that use GTK to render twemoji (and probably other things, given how X11 fonts are handled these days) are failing to correctly render the emojis at the correct size. I wonder if the viewBox mentioned in #84 is causing the problem?

The thing where I can't seem to make Noto not the default font no mater what XML I write for fontconfig (isn't twemoji supposed to make that Bitstream Vera?) is infuriating and when I figure out HOW that's happening, I'm filing a bug against the Noto fonts to stop doing it. It's messing with my preferred default Monospace font.

Anyway, it's a Debian system, so have some reportbug style info:

I totally agree with your point of view @knghtbrd

In my case, when I upgraded from debian 11 to debian 12 emacs started to display the noto-color-emoji, and I was unable to successfully install the twemoji or twitter color emoji

That is very sad for me, specially because firefox and matrix (client element.io) use the twitter emojis, so when I copy paste from these three systems, and when they enter emacs, they look more "soulless, lifeless, emotionless"

I tried installing the package, and trying to display the font in libreoffice, but it does not render, in this case, I installed the font bundled in firefox and thunderbird ( /usr/lib/firefox-esr/fonts/TwemojiMozilla.ttf /usr/lib/thunderbird/fonts/TwemojiMozilla.ttf )

but the same happens if I do

[2023-08-11 Fri 14:01:48] $ sudo dpkg -i fonts-twemoji-svginot_14.0.2-1_all.deb

and select the new available Twitter Color Emoji

libreoffice writer 7.4.7.2 (default of debian stable)

• line 1: Symbola
• line 2: Noto Color Emoji (when apt install fonts-recommended which installs fonts-noto-color-emoji package)
• line 3: Twitter Color Emoji (from this package)
• line 4: Twemoji Mozilla (from the ttf)

almost two hours have gone with this, I hope next one that read this take a step further, and I hope this way we collectively solve it :)

Waw, I finally understood what happened; so before I upgraded from debian11 to debian12 I saved a zfs snapshot, and placed it (with zfs send receive) now in another laptop, so I played a little bit with that snapshot:

• M-x describe-char from emacs, showed that it was using the google fonts
• tried there apt remove fonts-noto-color-emoji and discovered that then emacs was using symbolica fonts
• went to the debian changelog of https://packages.debian.org/sid/fonts-noto-color-emoji which is https://metadata.ftp-master.debian.org/changelogs//main/f/fonts-noto-color-emoji/fonts-noto-color-emoji_2.038-1_changelog and found this text This major update does not introduce new emoji, but revises almost 1000 emoji ; went to https://blog.emojipedia.org/android-emoji-changelog-july-2021/ and discovered that for example, the teddy bear emoji was in reality a specific from google one in emacs, and different to the twitter one
  • here is the info in the previous version (which is similar to the twitter one) https://emojipedia.org/google/android-11.0-december-2020-feature-drop/information
  • and here is the info emoji, which is more different to the twitter one https://emojipedia.org/google/android-12.0/information

conclusion: I thought twemoji color font was there in debian11 and disappeared on debian12, but I got confused on how similar they were (google noto vs twitter emoji) in debian11 release, and now they differ more in debian12
