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.
** No longer affects: fonts-noto-cjk (Ubuntu Cosmic)
** Description changed:
[Impact]
Due to Japan's new era, a Unicode character has been introduced which
represents the era name (Reiwa) as one single character. 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:
+ Install from {bionic,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
+ sudo locale-gen zh_HK.UTF-8
* Run this command:
- LC_CTYPE=zh_HK.UTF-8 fc-match
+ LC_CTYPE=zh_HK.UTF-8 fc-match
- and find that it returns:
+ and find that it returns:
- NotoSansCJK-Regular.ttc: "Noto Sans CJK HK" "Regular"
+ 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.
