Bug Description

New install of 18.04 and thunderbird is showing weird images in odd places for some email. See screen shot for example. In this case it is a weird rainbow, but I have also seen other things like a big stop sign and other strange stuff.

Emoji support is inconsistent:
- google chrome title is good
- firefox title is good
- google chrome contents, is bad, black&white ascii icon
- fiefox contents, is ok, not the same icon as in the title
- thunderbird content is ok, but too huge

What you're looking at there is probably unicode character 🌈
maybe Dimitri can confirm this.

The expected output is the same as opening https://launchpad.net/~xnox in Firefox, note the title bar, and the username.

Note there is a bug in Chrome/Chromium, where title bar shown correctly, but not the contents.

Ultimately this is Ubuntu Desktop bug. Whilst I love the oversized rainbows, it should be more space conscious than that.

The Thunderbird part in a duplicate of bug #1761844. Upstream Thunderbird says it will be fixed in version 60.

A quick workaround is to install fonts-symbola, as mentioned before, that will make Thunderbird use the emojis from their, but they are black and white.

Dimitri John Ledkov (xnox) wrote :

The expected behaviour is a colorful emoji though. In the body of google chrome/chromium too... Not the black&white ones.

Basically, gnome-terminal (or any other fully gtk3 native app) gets these right. But the listed browsers is a mixed bag result.

Dimitri, see my comment 12 on bug 1761844 which points out that is likely bug 1644021 which I helped fix in the beta PPA, but I don't handle Firefox/Thunderbird uploads directly to Ubuntu. You're welcome to talk to Chris about this issue though…

Jeremy Bicha (jbicha) wrote :

Web browsers have their own system for rendering text and therefore color emoji. Firefox currently uses a version of EmojiOne but is switching to the Twitter emoji set. See https://bugzilla.mozilla.org/1358240

Honestly, the bug report you filed is too broad and in some cases is already duplicated by existing bugs.

For reference, you might find this page interesting (it's a large page):

Ubuntu 18.04 LTS installs the Google emoji font by default and that page does actually display correctly for me with Firefox. Web pages can specify a particular color emoji font though. Therefore, you will see different emoji sets on different web pages and that's not really a bug.

no longer affects: ubuntu-meta (Ubuntu)

This looks fine in the latest stable chromium on bionic (and in the snap too). See attached screenshot. The only place where the rainbow is not rendered correctly is in the tab handle, but that's a different issue than the one originally reported.

Changed in chromium-browser (Ubuntu):
status: New → Fix Released

Other unicode characters and emojis are rendered correctly in the tab handle (see for example https://launchpad.net/~popey), but the rainbow emoji isn't. Not sure what's so special about that one.

This is fixed in Thunderbird 60 which will be in Ubuntu soon. I'm marking this a duplicate of bug 1761844.
