Creating and supporting OpenType fonts for the Khmer script

This document presents information that will assist font developers in creating fonts for Khmer script languages covered by Unicode 3.1. Font developers will learn how to encode complex script features in their fonts, choose character sets, organize font information, and use existing tools to produce Khmer fonts. Registered features of Khmer scripts are defined and illustrated, encodings are listed, and templates are included for compiling Khmer layout tables for OpenType fonts.

This document also presents information about the Khmer OpenType shaping engine of Uniscribe, an operating system component responsible for text layout.

In addition to being a primer and specification for the creation and support of Khmer fonts, this document is intended to more broadly illustrate the OpenType Layout architecture, feature schemes, and operating system support for shaping and positioning text.
