Thaana OpenType Specification

Creating and supporting OpenType fonts for the Thaana script
This document presents information that will assist font developers in creating fonts for the Thaana script covered by the Unicode Standard 3.1. Thaana script is used to write the Dhivehi language and consists of base glyphs, vowels and a set of dotted letters used to transcribe Arabic. 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 Thaana fonts. Registered features of the Thaana script are defined and illustrated, encodings are listed, and templates are included for compiling Thaana layout tables for OpenType fonts
This document also presents information about the Thaana 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 Thaana fonts, this document is intended to more broadly illustrate the OpenType Layout architecture, feature schemes, and operating system support for shaping and positioning text.
