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.

This feature turns capital characters into small capitals. It is generally used for words which would otherwise be set in all caps, such as acronyms, but which are desired in small-cap form to avoid disrupting the flow of text.

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 the default (current) forms with the historical alternates, e.g. the long form of s or the old Fraktur k.

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

Replaces default alphabetic glyphs with the corresponding ordinal forms for use after figures.

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.

This feature turns lowercase characters into small capitals. Forms related to small capitals, such as oldstyle figures, may be included.

Stylistic alternatives grouped as sets.
