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.

Shifts various punctuation marks up to a position that works better with all-capital sequences or sets of lining figures; also changes oldstyle figures to lining figures.

This feature replaces default character glyphs with corresponding swash glyphs in a specified context. Note that there may be more than one swash alternate for a given character.

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.
