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.

The version of fonts-noto-cjk in the stable releases does not support the new character, which is what motivates a backport of the eoan fonts-noto- cjk version. The proposed SRU is in line with the meta bug #1828884. This means an upgrade of Noto Sans CJK from version 1.004 to 2.001, and it will bring a few other changes in the bargain. Most notably a new set of Hong Kong fonts has been added to the previous ones (simplified and traditional Chinese, Japanese, and Korean). Attached to this bug report please see the file noto-sans-cjk-news.txt with upstream's detailing of the changes. [Test Case] Install from {bionic,cosmic,disco}-proposed: - fonts-noto-cjk - fonts-noto-cjk-extra - language-selector-common - language-selector-gnome 1. The Reiwa glyph -------------------------- Visit http://people.ubuntu.com/~gunnarhj/square-era-name-reiwa.html and find that a proper Japanese character, and not a tofu, is shown. 2. Presence and configuration of HK fonts ----------------------------------------- (This also bears on the language-selector changes.) * Install the Hong Kong locale: sudo locale-gen zh_HK.UTF-8 * Run this command: LC_CTYPE=zh_HK.UTF-8 fc-match and find that it returns: NotoSansCJK-Regular.ttc: "Noto Sans CJK HK" "Regular" 3. General use -------------- Browse some web sites with Chinese, Japanese or Korean contents and confirm that the upgrade does not cause any font rendering issues. [Regression Potential] This somewhat aggressive SRU proposal is based on trust in Google and Adobe as solid upstream providers of these fonts. Version 2.000 (which includes most of the changes) was released in November 2018, while version 2.001 (with the Reiwa glyph) was released in April 2019. Serious problems should have been known by now. The upstream bug tracker gives no cause for concern: https://github.com/googlefonts/noto-cjk/issues It may be worth mentioning that the fonts are provided as OTC files, and we don't compile those files ourselves. Hence just patching the new glyph would not be a practicable option. It would be easy to reverse this upgrade, if regressions would be reported. Basically we are talking about 7 files on the file system. [Other Info re. eoan] Since Debian hasn't packaged this yet, we have created a modified .orig.tar.xz file where 7 .ttc files (plus NEWS and HISTORY) differ from version 1:20181130+repack1-1~exp1, i.e. the latest Debian upload. There is no other Ubuntu/Debian delta, so as soon as Debian has catched up, it will be fine to start syncing again.
