The feature should be processed as the first feature processed, and should be processed only when it is called. This feature permits such composition/decompostion. Additionally, it may be preferable to compose two characters into a single glyph for better glyph processing. 'ss20' provide a mechanism for glyphs in these sets to be associated via GSUB lookup indexes to default forms and to each other, and for users to select from available stylistic sets.įunction: To minimize the number of glyph alternates, it is sometimes desired to decompose a character into two glyphs. Individual features numbered sequentially with the tag name convention 'ss01' 'ss02' 'ss03'. Examples of fonts including stylistic sets are Zapfino Linotype and Adobe's Poetica. Glyphs in stylistic sets may be designed to harmonise visually, interract in particular ways, or otherwise work together. multiple variants for lowercase letters in a Latin font. The glyph for ct replaces the sequence of glyphs c t, or U+322E (Kanji ligature for 'Friday') replaces the sequence U+91D1 U+66DC U+65E5.įunction: In addition to, or instead of, stylistic alternatives of individual glyphs (see 'salt' feature), some fonts may contain sets of stylistic variant glyphs corresponding to portions of the character set, e.g. This feature covers those ligatures which may be used for special effect, at the user's preference.

The user applies this feature to Industria to get the alternate form of g.įunction: Replaces a sequence of glyphs with a single glyph which is preferred for typographic purposes. This feature replaces the default forms with the stylistic alternates. As in the case of swash glyphs, there may be more than one alternate form. In Caflisch Script, o is replaced by o.alt2 when followed by an ascending letterform.įunction: Many fonts contain alternate glyph designs for a purely esthetic effect these don't always fit into a clear category like swash or historical. Used in script typefaces which are designed to have some or all of their glyphs join. The application can use this feature to automatically access the superior figures (more legible than scaled figures) for footnotes, or the user can apply it to Mssr to get the classic form.įunction: In specified situations, replaces default glyphs with alternate forms which provide better joining behavior. The user applies this feature to turn 2.o into 2.o (abbreviation for secundo).įunction: Replaces lining or oldstyle figures with superior figures (primarily for footnote indication), and replaces lowercase letters with superior letters (primarily for abbreviated French titles).

One exception to the follows-a-figure rule is the numero character (U+2116), which is actually a ligature substitution, but is best accessed through this feature. 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.įunction: Replaces default alphabetic glyphs with the corresponding ordinal forms for use after figures. This feature enables localized forms of glyphs to be substituted for default forms. In some cases the localized form differs only subtly from the script 'norm', in others the forms are radically distinct. For example, a number of letters in the Bulgarian and Serbian alphabets have forms distinct from their Russian counterparts and from each other. The glyph for ffl replaces the sequence of glyphs f f l.įunction: 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. This feature covers the ligatures which the designer/manufacturer judges should be used in normal conditions. The user enters 3/4 in a recipe and gets the threequarters fraction.įunction: Replaces a sequence of glyphs with a single glyph which is preferred for typographic purposes. A user inputs the P in Poetica, and is presented with a choice of the four standard capital forms, the eight swash capital forms, the initial capital form and the small capital form.įunction: Replaces figures separated by a slash with 'common' (diagonal) fractions. Since many-to-one substitutions are not covered, ligatures would not appear in this table unless they were variant forms of another ligature. This serves several purposes: An application may not support the feature by which the desired glyph would normally be accessed the user may need a glyph outside the context supported by the normal substitution, or the user may not know what feature produces the desired glyph. Function: This feature makes all variations of a selected character accessible.
