Breaks colored emoji in Gnome 3.26? about fedora-better-fonts HOT 9 CLOSED

Do you have some application installed to test emojis in Gnome notifications? I'm using Telegram Desktop with native notifications enabled in the settings. I remember that emojis didn't work after installing fontconfig-enhanced-defaults and fontconfig-font-replacements, but I made some changes since then and now they do work again. The changes I made were not meant to fix the emoji issue, but if you could confirm that emojis don't appear in Gnome notifications on your system I might be able to help you. However, I must note that not all emojis are displayed in color on this page on my system, so some font replacements seem to interfere with this.

What might just be enough is editing /etc/fonts/conf.d/52-latin-free.conf to include <family>emoji</family> as the second option for serif and non-serif. This should default to Noto Color Emoji (at least it does on my system). Otherwise just set it to <family>Noto Color Emoji</family> or your personal favorite. Just don't put it as the first option, as this might give issues. The relevant part:

  <!-- ## serif ## -->
  <alias>
    <family>serif</family>
    <prefer>
      <family>Noto Serif</family>
      <family>emoji</family>
      <family>DejaVu Serif</family>
      <family>Tinos</family>
      <family>Liberation Serif</family>
      <family>Nimbus Roman</family>
    </prefer>
  </alias>
  <!-- ## sans-serif ## -->
  <alias>
    <family>sans-serif</family>
    <prefer>
      <family>Noto Sans</family>
      <family>emoji</family>
      <family>Arimo</family>
      <family>Liberation Sans</family>
      <family>DejaVu Sans</family>
      <family>Nimbus Sans</family>
      <family>Open Sans</family>
    </prefer>
  </alias>

Thanks! Unfortunately, no dice. I still see no emojis in Gnome itself (tried the Characters app and GPaste's gnome shell extension), just blank space.

What's interesting is that I see all colored emojis in the page you linked when I have this installed. When I don't, they're all black and white.

So, the current status is:

• With this installed, I see no color emojis (just blank space) in Gnome apps, colored emojis here.
• With this uninstalled, I see color emojis in Gnome apps, black and white emojis here.

Very unsure what's going on...

What happens if you remove fontconfig-enhanced-defaults? Because I did those enhancements myself, so that might be it. Maybe it’s the setting for bitmap fonts. I'll tell you what to change if it works.

Yeah, removing fontconfig-enhanced-defaults brings back emojis in Gnome apps 😄

Nice. What you're missing now is proper cleartype-like rgb antialiasing. It's either disabled, or you should see obvious color fringing around text edges. The easiest way to enable it again is to install fontconfig-enhanced-defaults again and edit /etc/fonts/conf.d/10-enhanced-defaults.conf by removing this part:

<edit mode="assign" name="embeddedbitmap">
            <bool>false</bool>
</edit>

This is not what I did, but that would require creating multiple files and symbolic links, so this is easier to explain. I think you can do ln -s /usr/share/fontconfig/conf.avail/70-no-bitmaps.conf /etc/fonts/conf.d/ to replace the missing part without losing emoji support but it's not strictly necessary. To undo, simply run rm /etc/fonts/conf.d/70-no-bitmaps.conf. Fedora does this per font in 25-no-bitmap-fedora.conf instead of for all fonts as 70-no-bitmaps.conf does.

Thanks @makruiten! That works. I also symlinked 70-no-bitmaps.conf, though I am unsure how this affects the end result. Chrome still uses black & white emojis, but that was the case before.

Edit: Switching the emoji font fixes Chrome, so all is working. Thanks again!

I have removed 10-enhanced-defaults.conf file from fontconfig-enhanced-defaults package and replaced it with symlinks to 10-sub-pixel-rgb.conf, 11-lcdfilter-default.conf and 70-no-bitmaps.conf. It's a bit hacky (I'm providing symlinks to files from fontconfig package) but it seems to work.

Could you please test new package to see if it fixes your problem?

Thanks @silenc3r. Reverted all my changes to try it out and I can confirm everything is working well in the latest version.
