An issue with khmer unicode in sublime text 3 (3176)
Did you try with ST 3207? It includes some fixes for some unicode stuff.
I apologize, but I’m not familiar with Khmer. How should the section in the yellow look? Could you paste the text into the forum here to allow users to copy and paste?
As @deathaxe mentioned, we did fix some issue with ST 3.2, so build 3207 would be a better test target.
