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.

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.

Some ligatures were in common use in the past, but appear anachronistic today. Some fonts include the historical forms as alternates, so they can be used for a 'period' effect. This feature replaces the default (current) forms with the historical alternates.

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.

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.
