Localized Forms

Tag: locl

Function: Many scripts used to write multiple languages over wide geographical areas have developed localized variant forms of specific letters, which are used by individual literary communities. For example, a number of letters in the Bulgarian and Serbian alphabets have forms distinct from their Russian counterparts and from each other. In some cases the localized form differs only subtly from the script 'norm', in others the forms are radically distinct. This feature enables localized forms of glyphs to be substituted for default forms. The user applies this feature to text to enable localized Bulgarian forms of Cyrillic letters; alternatively, the feature might enable localized Russian forms in a Bulgarian manufactured font in which the Bulgarian forms are the default characters.

Stylistic Alternates

Tag: salt

Function: Many fonts contain alternate glyph designs for a purely esthetic effect; these don't always fit into a clear category like swash or historical. As in the case of swash glyphs, there may be more than one alternate form. This feature replaces the default forms with the stylistic alternates. The user applies this feature to Industria to get the alternate form of g.

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.

Akhands

Tag: akhn

Function: Preferentially substitutes a sequence of characters with a ligature. This substitution is done irrespective of any characters that may precede or follow the sequence. In complex scripts like Devanagari (Indic), the sequence Ka, Halant, Ssa should always produce the ligature Kssa, irrespective of characters that precede/follow the above given sequence. The Kssa is identified in Devanagari as an Akhand character (meaning unbreakable).

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 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.

Conjunct Forms

Tag: cjct

Function: This feature allows for control over re-ordering of reph and pre-pended matras in case of consonants that do not take half forms yet do form conjunct ligatures in combination with certain following consonants.

Half Forms

Tag: half

Function: Produces the half forms of consonants in Indic scripts. In Hindi (Devanagari script), the conjunct KKa, obtained by doubling the Ka, is denoted with a half form of Ka followed by the full form.

Nukta Forms

Tag: nukt

Function: Produces Nukta forms in Indic scripts. In Hindi (Devanagari script), a consonant when combined with a nukta gives its nukta form.

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.

Rakar Forms

Tag: rkrf

Function: Produces conjoined forms for consonants with rakar in Devanagari and Gujarati scripts.

Reph Form

Tag: rphf

Function: Substitutes the Reph form for a consonant and halant sequence. In the Devanagari (Indic) script, the consonant Ra possesses a reph form. When the Ra is a syllable initial consonant and is followed by the virama, it is repositioned after the post base vowel sign within the syllable, and also substituted with a mark that sits above the base glyph.

Vattu Variants

Tag: vatu

Function: Substitutes ligatures for conjuncts made up of base consonants with consonants that have vattu forms. In the Devanagari (Indic) script, the consonant Ra takes a vattu form, when it is not the syllable initial consonant in a conjunct. This form ligates with the base consonant as well as half forms of consonants.
