Not only Khmer Unicode can embed on FireFox3.5, Safari, Opera, Chrome... but Limon fonts, ABC Zero Space fonts also can embed on them too for now.
I have experience with it just today since i saw and try with the next generation of CSS , CSS3.
It is very great for Web Masters or Developers.
Whoever can read the news on the net very well even if they do't have Khmer fonts.
