All font include Khmer and Latin alphabets, and they have equivalent sizes for Khmer and English alphabets, so that when texts mix both it is not necessary to have different size points of the text for each language. This makes localization possible. Khmer OS System is our system font. It is hinted, so that it can be used and clearly understood in small sizes. If you are using MS Windows, we recommend that you install this font before any other Khmer fonts, as the first Khmer Unicode font installed in the system is used by MS Office as a default when you type a Khmer characters and the current font does not include Khmer characters.
We have also developed a a couple of hand-writing fonts. Download and try Khmer OS Freehand and Khmer OS Fasthand. Our Moul font is Khmer Os Moul. If you like old style text, give KhmerOS Metal Chrien a try.
To install the fonts on Windows, just copy them to the c:\windows\fonts directory.
