Sawasdee krap to you, and of course it's possible! When you run Chrome in this build, you're basically running it in a minimal Arch installation inside a Docker container. The image used for that is pulled from my Docker hub repo, I've updated it now to include Thai fonts as well. You'll need to run this command in an SSH session:
# docker pull escalade1/arch-chrome
The next time you launch Chrome, you should be all set

Sawasdee and Khob Khun krub (Thank you)
You're very helpful. Chrome can display Thai font now. I can watch my local streaming service with Thai subtitle.
But I notice somethings very weird about Youtube. I hope to use this with Youtube leanback too for watching Thai MV and local content mostly. But if I choose to go to http://youtube.com/tv directly, video can't be played at all. It will play only if I first play a video in youtube.com (normal desktop version) first and pause it. Then go open http://youtube.com/tv tab, now video playing fine. I have to do this everytime I open Chrome.
Anyway, your work is very great. Very appreciated.
Khob Khun krub agin. 
Ps. It seems LibreELEC's backup function doesn't work with your build.
