[Bug 1575555] Re: Chrome/Chromium use "Thin" as default font weight

[Gunnar Hjalmarsson]

** Description changed:

  [Impact]
  
  Chromium and Google Chrome use "Thin" as the default Noto Sans CJK font
  weight, which makes some Chinese and Japanese web pages difficult to
  read, and thus gives a bad user experience.
  
  The fonts-noto-cjk version in the PPA
  
  https://launchpad.net/~gunnarhj/+archive/ubuntu/fonts-noto-cjk
  
- installs 36 separate font files instead of a bundled OTC file. This
- works around the Chromium/Chrome issue.
+ installs 7 weight specific font files instead of a single "super" file.
+ This works around the Chromium/Chrome issue.
  
  [Test Case]
  
  To reproduce the bug:
  
  * Install Chromium or Google Chrome.
  * Go to <http://www.gamer.com.tw> and notice the very thin characters.
  * Install fonts-noto-cjk from the PPA and notice the difference.
  
  [Regression Potential]
  
- Due to ISO space concerns, the solution includes the creation of the
- fonts-noto-cjk-extras binary, which will not be seeded. fonts-noto-cjk
- installs only the 8 most important font files, while the rest are
- installed by fonts-noto-cjk-extras. Consequently 28 fonts will be
- dropped when the 16.04 users upgrade to the new fonts-noto-cjk package.
- However,
- 
- - they will be prompted to install fonts-noto-cjk-extras via Language
-   Support,
- 
- - fixing the Chromium/Chrome issue carries greater weight, and
- 
- - it's not a regression compared to 14.04 or 15.10, since the previous
-   package for rendering Chinese contents (fonts-droid) does not include
-   all those font weights.
+ This is about another font packaging form, without any change in glyph
+ coverage, so the the regression risk should be low.
  
  [Original description]
  
  The package seems to only "thin" variant of the font, which makes it
  very unreadable in applications such as Chrome (when it has to fall back
  on Chinese fonts on a mostly-English page). I had to remove the package
  and then manually download the font from Google website and install it
  to make the regular weight available
  
  Release: 16.04 LTS
  Package Version: 1.004+repack1-1
  Expected: All weights of the noto cjk font to be installed
  Happened: Only the "thin" weight of the font seems to be installed

** No longer affects: language-selector (Ubuntu Xenial)
