Contextual Ligatures

Tag: clig

Function: Replaces a sequence of glyphs with a single glyph which is preferred for typographic purposes. Unlike other ligature features, clig specifies the context in which the ligature is recommended. This capability is important in some script designs and for swash ligatures. The glyph for ft replaces the sequence f t in Bickham Script, except when preceded by an ascending letter.

Above-Base Forms

Tag: abvf

Function: Substitutes the above-base form of a vowel. In complex scripts like Khmer, the vowel OE must be split into a pre-base form and an above-base form. The above-base form of OE would be substituted to form the correct piece of the letter that is displayed above the base consonant.

Above-Base Mark Positioning

Tag: abvm

Function: Positions marks above base glyphs. In complex scripts like Devanagari (Indic), the Anuswar needs to be positioned above the base glyph. This base glyph can be a base consonant or conjunct. The base glyph and the presence/absence of other marks above the base glyph decides the location of the Anuswar, so that they do not overlap each other.

Above-Base Substitutions

Tag: abvs

Function: Substitutes a ligature for a base glyph and mark that's above it. In complex scripts like Kannada (Indic), the vowel sign for the vowel I which a mark, is positioned above base consonants. This mark combines with the consonant Ga to form a ligature.

Below-Base Forms

Tag: blwf

Function: Substitutes the below-base form of a consonant in conjuncts. In complex scripts like Oriya (Indic), the consonant Va has a below-base form that is used to generate conjuncts. Given a sequence Gha, Virama (Halant), Va; the below-base form of Va would be substituted to form the conjunct GhVa.

Below-Base Mark Positioning

Tag: blwm

Function: The form that consonants appear below the base glyph. Consonants in below-base form appear in Bengali syllables after the ones that form the base glyph. Below-base forms are represented by the non-spacing mark glyph.

Below-Base Substitutions

Tag: blws

Function: Produces ligatures that comprise of base glyph and below-base forms. In the Malayalam script (Indic), the conjunct Kla, requires a ligature which is formed using the base glyph Ka and the below-base form of consonant La. This feature can also be used to substitute ligatures formed using base glyphs and below base matras in Indic scripts.

Glyph Composition/Decomposition

Tag: ccmp

Function: To minimize the number of glyph alternates, it is sometimes desired to decompose a character into two glyphs. Additionally, it may be preferable to compose two characters into a single glyph for better glyph processing. This feature permits such composition/decompostion. The feature should be processed as the first feature processed, and should be processed only when it is called. In Syriac, the character 0x0732 is a combining mark that has a dot above AND a dot below the base character. To avoid multiple glyph variants to fit all base glyphs, the character is decomposed into two glyphs...a dot above and a dot below. These two glyphs can then be correctly placed using GPOS. In Arabic it might be preferred to combine the shadda with fatha (0x0651, 0x064E) into a ligature before processing shapes. This allows the font vendor to do special handling of the mark combination when doing further processing without requiring larger contextual rules.


Tag: dist

Function: Provides a means to control distance between glyphs. In the Devanagari (Indic) script, the distance between the vowel sign U and a consonant can be adjusted using this.

Pre-base Forms

Tag: pref

Function: Substitutes the pre-base form of a consonant. In the Khmer script, the consonant Ra has a pre-base subscript form subscript called Coeng Ra. When the sequence of Coeng followed by Ra, its pre-base form is substituted.

Pre-base Substitutions

Tag: pres

Function: Produces the pre-base forms of conjuncts in Indic scripts. It can also be used to substitute the appropriate glyph variant for pre-base vowel signs. In the Gujarati (Indic) script, the doubling of consonant Ka requires the first Ka to be substituted by its pre-base form. This in turn ligates with the second Ka. Applying this feature would result in the ligaturised version of the doubled Ka.

Post-base Forms

Tag: pstf

Function: Substitutes the post-base form of a consonant. In the Gurmukhi (Indic) script, the consonant Ya has a post base form. When the Ya is used as the second consonant in conjunct formation, its post-base form is substituted.

Post-base Substitutions

Tag: psts

Function: Substitutes a sequence of a base glyph and post-base glyph, with its ligaturised form. In the Malayalam (Indic) script, the consonant Va has a post base form. When the Va is doubled to form a conjunct- VVa; the first Va [base] and the post base form that follows it, is substituted with a ligature.
