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.

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 selected figures which follow a slash with denominator figures.

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 oldstyle to the default lining form.

Replaces selected figures which precede a slash with numerator figures, and replaces the typographic slash with the fraction slash.

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

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

Replaces figure glyphs set on uniform (tabular) widths with corresponding glyphs set on glyph-specific (proportional) widths. Tabular widths will generally be the default, but this cannot be safely assumed. Of course this feature would not be present in monospaced designs.

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

Replaces lining or oldstyle figures with inferior figures (smaller glyphs which sit lower than the standard baseline, primarily for chemical or mathematical notation). May also replace lowercase characters with alphabetic inferiors.

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.

Replaces lining or oldstyle figures with superior figures (primarily for footnote indication), and replaces lowercase letters with superior letters (primarily for abbreviated French titles).

Replaces figure glyphs set on proportional widths with corresponding glyphs set on uniform (tabular) widths. Tabular widths will generally be the default, but this cannot be safely assumed. Of course this feature would not be present in monospaced designs.
