How to install Noto Sans CJK fonts for reMarkable Tablet

Install CJK fonts to reMarkable Tablet.md

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.

1. Go to Preference > Storage > Enable USB web interface (Beta).
2. Connect reMarkable with your PC via a microUSB cable.
3. SSH to the device as user "root" using the password find in Preference > About. e.g. ssh [email protected]
4. Download "NotoSansCJK[you language]-Regular.otf" from https://www.google.com/get/noto/help/cjk/ *note, there is limited space on the device, so do not sue "Super OpenType/CFF Collection (Super OTC)", an language-specific OTC is ok.
5. Copy (using SCP or whateever tools you like) to /usr/share/fonts/opentype/
6. Make sure the uploaded font file has the corrent permission (it should be 644).
7. Run fc-cache -f -v to refresh to font cache.
8. Reboot the device reboot. (or use the physical button)
9. Read a book in your language, set the font as "Noto Sans" in Text settings.
10. Done!

• Note: CJK Serif Fonts does not work even if I have installed OTF on the device and select Noto Serif, not sure why. Noto Sans is good enough though!

Thanks so much, this worked for me! (Using .ttf instead of .otf, as in the comment above.)

Thanks the instructions!
I'm following same step by adding a new font (https://typeof.net/Iosevka/).
But it didn't appear in the Text Settings -> Font of documents (EPUB, Text).
What I could be missing?

@freizl you probably should reach out to ReMarkable, this was written in 2018, it was a hack to support CJK fonts, and back then ReMarkable was a small start-up, but now it's 2024, IMO it is not acceptable that they don't support CJK fonts.

Cool. thanks!
