Detailed Description

In order to reduce the font size in Noto CJK fonts, we plan to switch to use the variable fonts by default.

  1. Split the google-noto-cjk-fonts package into google-noto-cjk-sans-fonts and google-noto-cjk-serif-fonts, and provide the variable fonts in google-noto-cjk-sans-vf-fonts and google-noto-cjk-serif-vf-fonts.
  2. Drop several sub packages which are not installed by default from the google-noto-cjk-fonts package.
  3. Install the Noto CJK Variable Fonts by default.
