reMarkable is a paper tablet by https://remarkable.com/.

The reMarkable tablet is the best e-paper in the market. However, it does not have built-in support for CJK (Chiniese, Korean and Japanese) users.

Luckily, this could be resolved by installing CJK fonts on the tablet.

Go to Preference > Storage > Enable USB web interface (Beta).
Connect reMarkable with your PC via a microUSB cable.
SSH to the device as user "root" using the password find in Preference > About. e.g. ssh [email protected]
Download "NotoSansCJK[you language]-Regular.otf" from *note, there is limited space on the device, so do not sue "Super OpenType/CFF Collection (Super OTC)", an language-specific OTC is ok.
