There are two fonts:
1. “KOS Cheung Da” is derived from the font named “Khmer OS System”.
2. “KOS Moul” is derived from the font named “Khmer OS Muol Light”.
Purpose of creation of these fonts is to differentiate between Khmer subscripts “ta” and “da” which currently makes significant confusion in reading.
Please download them below if you need them.
One more font is “KOS Listing“.
It can be used to make a list with numbering or lettering in Khmer.
It is already included in the download link above.
