By default, Linux Mint 17.1 “Rebecca” is using the Noto fonts, but the package for these fonts (fonts-noto) does not provide support for CJK (Chinese/Japanese/Korean). In other words, the rendering of text in these languages is done via a font fallback on the traditional Sans font.
A new package called fonts-noto-cjk, which provides Noto Sans CJK Version 1.001, was added to the Rebecca repositories today.
Because this package includes font configuration we would have wanted to test pre-RC, represents a 175MB download and takes a rough 450MB of HDD space once installed, it won’t be included by default in the stable release of Linux Mint 17.1.
Being in the repositories though, you can easily install it with a simple “apt install fonts-noto-cjk”.
If you find this package useful or if you encounter issues with it, whether your experience is positive or negative, don’t hesitate to comment and give us feedback on this.
