Here is a great tool to help those of you who don’t quite have a handle on Khmer Unicode, or if you are at a computer that has not yet installed Khmer Unicode.  Using JavaScript, Richard Ishida (the internationalization lead at the W3C) has put together a Khmer Unicode Character Picker that allows you to type Khmer Unicode simply by selecting the character you want with your mouse.
