Are you a Khmer? Generally use Khmer Unicode but cannot abandon Limon. Your Microsoft Office 2003 or 2007 allow you not to write sub-character of Khmer letters? Well, I find a file that is proven to be very useful.
With just a single (DOS) file, and come with two version of Normal.DOT/DOTM (Office Normal Template) and easy to install with just a single click and a single keystroke.
Just start it and choose which version of your Microsoft Office and hit Enter then voìla, here you can use Limon fonts really easy.
