** Description changed:

  Ubuntu Touch uses Kaiti style font as the main UI font for displaying
  Chinese, which is not optimal as nowadays operating systems all use
  Heiti style font for the UI, we should really change it asap.
  
  Currently there are two choices on Ubuntu, fonts-droid and wqy-microhei.
  Below I will list out the pros and cons.
  
  I am not too much in favour of using wqy-microhei, the reason being that
  it is basically a font that based on the Droid font
  (DroidSansFallbackFull.ttf to be exact). Upstream has not updated wqy-
  microhei for long time, so it lacks any new updates from the Droid font,
  although it may not be obvious to users. Advantage of wqy-microhei being
  its wider codepoint coverage, for example it also contains Japanese
  Kanas and Korean Hanguls in one font, the downside is it may be of lower
  quality than DroidSansFallbackFull.ttf due to its lack of maintenance in
  recent years.
  
  Another option is DroidSansFallbackFull.ttf, which is in the fonts-droid
  package. The advantage is it has coverage of CJK ext. A [1], which wqy-
  microhei does not provide. On the other hand, wqy-microhei has added
  some glyphs that the droid font does not provide, I don't have the exact
  number of that but I believe it's just a small number. The disadvantage
  is it does not include Korean Hangul, which can be remedied with another
  Korean font, and it's not our current concern anyway.
  
  Another possible disadvantage of wqy-microhei is it includes more latin
  characters, which may result to inconsistent glyphs being used.
  
+ Just a few days ago, Google released the Noto Sans CJK fonts. The
+ advantage of Noto is it takes care of different writing standard of
+ Traditional and Simplified Chinese. As a result the total file size is
+ much bigger. I haven't tried it on Ubuntu Touch so not sure how well it
+ renders. It's not yet available in fonts-noto [3].
