** Changed in: gtk4 (Ubuntu Oracular)
Status: Triaged => In Progress
** Description changed:
Impact
------
Ubuntu has included Google's color emoji font by default for years. Annually,
the Unicode Consortium releases a new Unicode standard with new emoji. Internet
communication platforms quickly adopt the new emoji and it's important that
those emoji also work on the latest Ubuntu release.
https://blog.emojipedia.org/whats-new-in-unicode-16-0/
This is a follow up to LP: #2083629 which updated the color emoji font
to support the new emoji.
This updates the GTK4 emoji chooser that can be used in apps like gnome-
text-editor
Test Case 1
---------
1. Be sure fonts-noto-color-emoji 2.042-1 is installed. On Ubuntu 24.04 LTS,
this is as simple as running
sudo apt install --mark-auto fonts-noto-color-emoji=2.042-1
For Ubuntu 24.10, you can download the .deb from
https://launchpad.net/ubuntu/+source/fonts-noto-color-emoji/2.042-1/+latestbuild/amd64
and then run something like
sudo apt install --mark-auto ./fonts-noto-color-emoji_2.042-1_all.deb
2. After installing the font, restart your computer.
3. Install the updated gtk4 packages.
4. Run gnome-text-editor. Right click in the text area and choose Insert
Emoji.
5. Search for fingerprint. No results should be shown.
Test Case 2
------
1. Be sure fonts-noto-color-emoji 2.047 is installed. On Ubuntu 24.10, this
font version should already be installed.
By the time this GTK3 update reaches noble-proposed, fonts-noto-color-
emoji 2.047 will likely be in noble-updates. If not, install it from
noble-proposed instead.
2. Restart your computer.
3. Install the updated gtk4 packages.
4. Run gnome-text-editor. Right click in the text area and choose Insert
Emoji.
5. Search for fingerprint. Click the blue fingerprint result. It should
be inserted into your document.
What Could Go Wrong
-------------------
- This SRU is limited to updating the data used to generate the GTK4 emoji
chooser.
+ This is roughly a backport of the emoji chooser update from GTK 4.16.8. This
was split from a full update to 4.16.8 for Oracular to simplify the SRU. Since
the upstream GTK developers only supports one stable series of GTK4 at a time,
this change was not included in any upstream 4.14.x release (for Ubuntu 24.04
LTS).
+
+ This SRU is limited to updating the data used to generate the GTK4 emoji
+ chooser.
If the emoji chooser is broken, people can:
1. Use the GNOME Characters app (installed by default) to choose emoji
instead and copy and paste them where needed.
2. Copy and paste emoji from the web, such as from https://emojipedia.org/
This doesn't affect gtk3 apps like gedit (which is not installed by
default for Ubuntu 24.04 LTS and 24.10).
Other Info
----------
We are also updating the gtk3 emoji chooser in LP: #2096777
This change could be backported to Ubuntu 22.04 LTS but the Ubuntu
Desktop team has limited capacity so we are encouraging people who care
about improvements like this to upgrade to Ubuntu 24.04 LTS.
Debian customizes the build in debian/rules using a copy of the binary
emojibase data in debian/missing-sources/ to build the emoji chooser
data from source (gtk upstream ships the output of that command
instead). (Yes, that still isn't ideal because the emojibase data is
itself binary data that some day should be built from source in Debian
too.)
Therefore to update the emoji chooser data, we only need to update the
emojibase copy instead of updating to the new gtk3 release or cherry-
picking upstream commits as patches.
