Solution is:
1. Create a fonts folder under the directory: /storage/.local/share/
- Enable ssh in libreelec services
- Connect as root with filezilla or whatever method prefer. From shell ssh connection you can just run:
# ssh root@yourlibreelecip then enter the password (default password is libreelec)
# mkdir -p /storage/.local/share/fonts/noto
- Copy your font archive (or font folders) into that directory.using pscp, scp, or filezilla etc etc, then;
- cd /storage/.local/share/fonts/noto
- Extract your font archive (# unzip Noto-hinted.zip), and clean up (# rm ./Noto-hinted.zip).
2. Re-launch the chrome addon, then go to chrome://settings/fonts
- Choose Advanced font settings - install the extension if you don't have it - now you should now be in business!
Tested and working (and persistent after reboot). Don't forget to choose the required fonts for the language script you need in the advanced font settings.
Stumbled upon this issue today - was mid-exam on a language course I paid $$ for, but had to be viewed via chrome. Had 'a moment' when the encoded characters displayed as squares. I HAD to solve it - so it's my 0-day solution. Libreelec is awesome, hope this post is useful to the developers and international folk.
