For example, 'Ka' and 'Ta', rather than just 'K' or 'T.'Д¬onsonant conjuncts (aka вЂњconjunctsвЂќ) - Ligatures of two or more consonants. Consonants may exist in different contextual forms and have an inherent vowel (usually, the short vowel 'a'). Below-base forms are represented by a non-spacing mark glyph.Д¬luster вЂ“ A group of characters that form an integral unit in Indic scripts, often times a syllable.Д¬onsonant - Each represents a single consonant sound. In the glyph sequence, the below-base form comes after the consonant(s) that form the base glyph. Layout operations are defined in terms of a base glyph, not a base character, since the base can often be a ligature.Д«elow-base form of consonants - A variant form of a consonant that appears below the base glyph. In 'degenerate' syllables that have no vowel (last letter of a word), the last consonant in halant form serves as the base consonant and is mapped as the base glyph. In Tamil, the last consonant of the syllable forms the base glyph. Akhand ligatures may be displayed in either half- or full-form.Д«ase glyph - The only consonant or consonant conjunct in the orthographic syllable that is written in its 'full' (nominal) form. Akhand ligatures have the highest priority and are formed first some languages include them in their alphabets. The following terms are useful for understanding the layout features and script rules discussed in this document.ДЄbove-base form of consonants вЂ“ A variant form of a consonant that appears above the base glyph.ДЄkhand ligatures - Required consonant ligatures that may appear anywhere in the syllable, and may or may not involve the base glyph.

For example, the location where the reph and pre-pended matra are re-ordered within a syllable cluster is affected by the presence of a half form. The new Indic shaping engine allows for variations in typographic conventions, giving a font developer control over shaping by the choice of designation of glyphs to certain OpenType features. In addition, registered features of the Tamil script are defined and illustrated with examples. While it does not contain instructions for creating Tamil fonts, it will help font developers understand how the Indic shaping engine processes Indic text. It contains information about terminology, font features and behavior of the Indic shaping engine in regards to the Tamil script. This document targets developers implementing Indic shaping behavior compatible with Microsoft OpenType specification for Indic scripts. The Tamil script has fewer consonants than other Indic scripts and has only one consonant conjunct. Tamil is also used in Sri Lanka, Singapore and parts of Malaysia. The Tamil script is used to write the Tamil language of the southern Indian state of Tamil Nadu, as well as minority languages like Badaga. This document presents information that will help font developers create or support OpenType fonts for Tamil script languages covered by the Unicode Standard.

#Tamil fonts update

While Indic fonts made according to the earlier recommendations will still function properly in the new versions of Uniscribe, font developers may choose to update their fonts, particularly if they wish to avoid certain limitations of the earlier implementation. Please note: This document reflects the changes made in 2005 recommendations for Indic-script OpenType font and shaping-engine implementations.
