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.

Replaces selected figures which follow a slash with denominator figures.

Replaces figures separated by a slash with 'common' (diagonal) fractions.

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.

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 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.

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.

Some fonts contain both a default form of zero, and an alternative form which uses a diagonal slash through the counter. Especially in condensed designs, it can be difficult to distinguish between 0 and O (zero and capital O) in any situation where capitals and lining figures may be arbitrarily mixed. This feature allows the user to change from the default 0 to a slashed form.
