Iskoola Pota contains layout information and glyphs to support all of the required features for the Sinhala script. Moving forward, developers should refer to this new specification. This feature is used in association with OpenType language system tags to trigger lookups that will select alternate glyphs needed for language-specific typographic conventions. Uniscribe makes as many calls to the OTL Services as there are features. The greatest variation among different Indian scripts is found in the rules for attaching dependent vowels to base characters OpenType layout engine — The library responsible for executing OpenType layout features in a font. Shaping engine – Code responsible for shaping input, classified to a particular script. Usually the different pieces appear in different positions relative to the base.

Cluster — A group of characters that form an integral unit in Indic scripts, oftentimes this corresponds to a syllable. The standard order for applying Sinhala features iskpotq in OpenType fonts: The meanings of the symbols are: This document presents foont that will help font developers in creating OpenType fonts for Sinhala script as covered by the Unicode Standard 6. Note that the input context for a feature may be the result of a previous feature having already been applied.

Introduction This document targets developers implementing shaping behavior compatible with the Microsoft OpenType specification for the Sinhala script. The descriptions which follow will help font developers understand the rationale for the Sinhala feature encoding model, and help application developers better understand how layout clients can divide responsibilities with operating system functions.

In the Sinhala engine, OpenType features are applied to the entire run after any reordering has been completed. The ront variation among different Indian scripts is found in the rules for attaching dependent vowels to base characters. The Iskoola Pota font uses this feature to position marks relative to the dont circle placeholder glyph. Terms The following terms are useful for understanding the layout features and script rules discussed in this document.

OpenType tag — A 4-byte identifier for script, language system or feature in the font. There are no open issues. The order of the lookups within each feature is also very iskppota. Starting in Windows 10, Sinhala will be supported by the Universal Shaping Engine rather than a stand-alone shaping engine. This feature is dont to position marks above base glyphs.

Layout operations are defined in terms of a base glyphnot a base characteras a ligature may act as a base. This document targets developers implementing shaping behavior compatible with the Microsoft OpenType specification for the Sinhala script. Would you like to provide feedback? Multiple features ikpota provided as an aid for font developers to organize the lookups they implement.

It is also used fknt write Pali and Sanskrit. The shaping engine next processes the GPOS glyph positioning table, applying features concerned with positioning. Because this could theoretically go on forever, an arbitrary limit of eight occurrences has been set. This feature may be used to adjust the positioning of glyph pairs.

The following tables list the registered tag names for scripts and language systems. It contains information about terminology, font features and fon of the Sinhala shaping engine. The OpenType lookups in a Sinhala font must be written to match glyph sequences after re-ordering has occurred. Character properties are used in parsing syllables and identifying their parts as well as determining whether any contextual reordering is required.

Regardless of the model an application chooses for supporting layout of complex scripts, Uniscribe requires a fixed order for executing features within a run of text to consistently obtain the proper basic form.

The font developer iskpkta consider the effects of re-ordering when creating the GPOS feature and lookup tables i. Analyzing the characters Processing split matras Reordering characters Applying OpenType GSUB izkpota to kskpota the correct glyph shape Applying OpenType GPOS features to position glyphs or marks The descriptions which follow will help font developers understand the rationale for the Sinhala feature encoding model, and help application developers better understand how layout clients can divide responsibilities with operating system functions.

The akhand ligature feature is used to create all required ligatures including touching consonants used in Pali and Sanskrit. The language system tag specifies a typographic convention associated with a language or linguistic subgroup.

The Sinhala script is used to write the Sinhala language. For instance, part of the matra may be placed at the beginning of the cluster and another part at the end iskptoa the cluster. This is achieved by calling features one-by-one in the standard order listed below.
