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. This feature covers those ligatures which may be used for special effect, at the user's preference.

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

Gives the user access to ornament glyphs (e.g. fleurons, dingbats and border elements), either by replacing the bullet character with a selection from the full set of available ornaments, or replacing specific "lower ASCII" characters with ornaments assigned to them.

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.

This feature replaces the default glyphs with corresponding forms designed specifically for titling. These may be all-capital and/or larger on the body, and adjusted for viewing at larger sizes.
