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!

Really appreciate this post. I just want to add a small update. I'm using Remarkable 2 (firmware version 3.8.2.1965). I copied NotoSansKR-Regular.ttf to /usr/share/fonts/ttf/ instead (in the Noto package I downloaded, I don't have any otf fonts) and refresh the font cache as instructed. It works like a charm! Thanks again!

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!
