This feature makes all variations of a selected character accessible. 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. Since many-to-one substitutions are not covered, ligatures would not appear in this table unless they were variant forms of another ligature.

When available, replaces default glyphs with alternate forms which provide better joining behavior.

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.

Replaces figures separated by a slash with 'common' (diagonal) fractions.

Replaces a sequence of glyphs with a single glyph, e.g. 'fi', 'fl'. This feature is enabled by default and cannot currently be disabled.

This feature changes selected figures from the default lining style to oldstyle form.

Replaces the default forms with stylistic alternates. Note that there may be more than one stylistic alternate for a given character.

Stylistic alternatives grouped as sets.

Replaces default character glyphs with corresponding swash glyphs. Note that there may be more than one swash alternate for a given character.
