** Description changed:
- This ships the latest Noto CJK fonts to the users in good time before
- the 19.10 release, and will help with the progress of the meta bug
- #1828884 which is about desired changes due to the new Japanese era
- Reiwa. Verson 2.001 includes glyphs for Reiwa.
+ [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:
+
+ - 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) differs
- from version 1:20181130+repack1-1~exp1, i.e. the latest Debian upload.
+ .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.
