Consonants may exist in different contextual forms, and have an inherent vowel (usually, the long vowel “A”). NOTE: The shape of the COENG is arbitrary and is not rendered.Ĭonsonant - Represents a single consonant sound. The COENG is always tied to the letter following it and is always handled as a unit with the following letter. U+17D2 (COENG) – Code point before a consonant or independent vowel, which causes the formation of the subscript form of that letter. Layout operations are defined in terms of a base glyph, not a base character, since the results of the shaping process are a series of glyphs. In Khmer, the first consonant or independent vowel of the syllable usually forms the base glyph. The following terms are useful for understanding the layout features and script rules discussed in this document.īase Glyph – The one and only consonant, independent vowel, or number in the syllable that is written in its “full” (nominal) form. 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. This document also presents information about the Khmer OpenType shaping engine of Uniscribe, the Windows component responsible for text layout. Registered features of the Khmer script are defined and illustrated, encodings are listed, and templates are included for compiling Khmer layout tables for OpenType fonts.

In this specification, 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. This document presents information that will help font developers create or support OpenType fonts for the Khmer script languages covered by the Unicode Standard.
