Possible backports to disco and bionic are available in this PPA:

Ok, after browsing through the news and thinking about it, I feel that this could potentially be SRUable. My rationale would be: the package is in main and typically an all-or-nothing package, where we can't cherry pick single pieces easily. So to keep our users up-to-date, there's no other choice but including a new upstream release.

Anyway, with my SRU hat on, I'm giving a +1 on getting this in. But as with any risky bits like this, I'd appreciate if we could keep the package in -proposed for a bit longer and, possibly, organizing a call-for-testing for it.

Thanks Łukasz! Sure, we'll call for testing when the packages are in -proposed.

At the moment they are in the upload queues. I uploaded fonts-noto-cjk to cosmic too 'for version technical reasons'. Not sure if that was necessary...

Hi Gunnar, Łukasz,

Thank you for your consideration!

I confirmed fixed for eoan. And I'm going to test bionic/disco, if package upload to proposed.

Note to other SRU members: since this upload is generally impossible to review, what I did is check if the binaries are matching what's in eoan and if the binaries are matching the contents from the upstream tarball.

Confirmed the test case for bionic and disco after having installed

- from bionic-proposed:
   fonts-noto-cjk 1:20190409+repack1-0ubuntu0.18.04
   fonts-noto-cjk-extra 1:20190409+repack1-0ubuntu0.18.04
   language-selector-common 0.188.3
   language-selector-gnome 0.188.3

   fonts-noto-cjk-extra 1:20190409+repack1-0ubuntu0.19.04
   language-selector-common 0.194.1
   language-selector-gnome 0.194.1

My tests included step 1, 2, and - FWIW - 3.

Call for testing
================

Since the proposed upgrade of fonts-noto-cjk affects most CJK users and includes changes beyond the glyphs for rendering the Reiwa character, we hope for help with testing by users who speak Chinese, Japanese and/or Korean before the packages are made available to all users via -updates.

Testing on the latest LTS, i.e. Ubuntu 18.04, is preferable, but also testing fonts-noto-cjk 1:20190409+repack1-0ubuntu* on 19.04 or even eoan helps.

These are the steps to install the new versions of the affected packages from bionic-proposed:

1. Enable bionic-proposed
-------------------------

* Open Software & Updates and select the "Developer Options" tab.

* Check the "Pre-released updates" option.

2. Update the package information on your system
------------------------------------------------

sudo apt update

3. Install/upgrade the packages
-------------------------------

sudo apt install fonts-noto-cjk* language-selector-*

4. Disable bionic-proposed
--------------------------

* Open Software & Updates and select the "Developer Options" tab.

* Uncheck the "Pre-released updates" option.

5. Update the package information on your system
------------------------------------------------

sudo apt update

With that your system is back to normal, except for those four packages from -proposed. You can confirm that you got the right versions by using this command:

dpkg-query -W fonts-noto-cjk* language-selector-*

It should show this info:

fonts-noto-cjk 1:20190409+repack1-0ubuntu0.18.04
fonts-noto-cjk-extra 1:20190409+repack1-0ubuntu0.18.04
language-selector-common 0.188.3
language-selector-gnome 0.188.3

Then I simply ask you to use your computer for your daily needs when dealing with CJK contents, and submit a comment here after a few days about your experience. Any kinds of comments are helpful, both "works well" and info about issues you stumble upon. Most important, of course, is that no new issues are introduced via this upgrade.

Thanks in advance for your help with this!

Would like to remind of the call för testing in comment #13.

Mitsuya has confirmed that the new Reiwa character is shown properly in the recently upgraded version of ibus-mozc (comment #6). Technically I verified the test case the other day (comment #12), and I have changed the tags accordingly. But as someone who don't speak any CJK language, my evaluation of what the characters look like is of limited value.

So it's highly desirable that some CJK users test the upgraded fonts packages, and submit comments here, before they are moved to -updates.

I've always have proposed turned on on my 19.04 box and haven't experienced any Chinese input/output issues with the new font.

Sorry for lately testing...

On disco and bionic, I found no problem with Japanese locale.

@gunnarhj- Has there been a call for testing made in places other than this bug report?

There is this message at ubuntu-devel-discuss:

https://lists.ubuntu.com/archives/ubuntu-devel-discuss/2019-July/018393.html

But it's a reply in a thread, and not so well highlighted.

Since I subscribed three relevant teams (Ubuntu CJK Testers, Ubuntu Japanese Team and Ubuntu Korean Team) to this bug, my thought has been that using the bug report ought to be fit for purpose.

I feel like this update has been in -proposed long enough now. Also, the fix has been verified and package used by 3 people at least (as seen in comments #14, #15 and #16), so that's already quite good. If no issues have been noticed so far, not sure if waiting any longer makes any sense.

Let me release.

The verification of the Stable Release Update for language-selector has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Shouldn't this be fixed in Xenial as well?

There are two reasons why I didn't propose it for Xenial too.

In Xenial Noto Sans CJK is not the default font in Ubuntu for rendering Japanese, but Takao is. So to support the rendering of the "square era name reiwa" glyph in Xenial, Takao is the package which should be handled at first hand.

Also, Xenial is the first cycle where we use fonts-noto-cjk in Ubuntu (for Chinese), and the introduction of that package with its somewhat demanding OTC packaging format forced us into a last minute upgrade of fontconfig.

https://lists.ubuntu.com/archives/ubuntu-devel/2016-April/039303.html

So without having tested, my gut feeling says that backporting fonts-noto-cjk to Xenial would be higher risk than was the case for Bionic.

It *was* used in Xenial though, and appears to be in main. It should be very much evaluated whether people are using it in xenial to display Japanese, and if that's the case, then it ought to be fixed there as well. It is possible a straight backport would work well there, since it's a font.

FWIW, I'm not making the call that it *should* be SRUed, but bringing it up for discussion.

It's in main in xenial since it's default for Chinese.

I would like to see some Japanese users chime in here.

One specific question is: How common is it that Japanese xenial users have uninstalled fonts-takao-pgothic and other fonts-takao packages in order to let rendering of Japanese text be handled by Noto Sans CJK JP?
