All Caps [cpsp]

Case Sensitive Forms [case]

This function formats the text in uppercase and adjusts spacing between all capital letters. It also applies the ‘Case Sensitive Forms’ feature which replaces certain characters with alternates that are better suited for all capital text, especially related to punctuation.

Contextual Alternates [calt]

This feature adapts the position of a glyph after its surrounding context. For instance, a dash placed between two uppercase letters or numbers will be replaced by an uppercase version of the dash, slightly higher. This feature is usually active by default in Adobe applications.

Tabular Lining Figures [tnum–lnum]

Based on the proportions of the capitals, lining figures have an invariable height. With the combination of the tabular spacing format, the width of each numeral is uniformized. This feature is useful when numerals need to all lined up. It facilitates the reading of numbers set within columns or tables. As some applications don’t have access to this feature, proportional figures are set as the default choice.

Fractions [frac]

With this feature, any numbers separated by a slash will automatically turn into a fraction. To fit in fraction configuration, numerals have been designed smaller and their weights have been adjusted to suit the typeface.

Ordinals [ordn]

This feature replaces any letter following a numeral with its matching superior letters. French language uses the ordinal indicators such as ‘er’ for 1er premier, while Spanish, Portuguese and Italian require the feminine and masculine ordinals ‘a,’ ‘o’ for 1º, 1ª. Ordinals are designed to match the weight of the typeface.

Slashed Zero [zero]

Originally created to avoid the confusion between the ‘0’ and the ‘O’, this feature substitutes all zeros in a selected text by a slashed form of the zero.

Proportional Oldstyle Figures [onum]

Tabular figures are all of equal width. They are only needed when the figures must all line up from one line to the next, as in a table. Proportional figures have varying widths, just like most letters; each number has a width appropriate to its design. Lining figures are all the same height, usually similar to that of capital letters. They are needed for use with all-capital settings.

Stylistics Set [ss08]

This feature replaces glyph(s) with stylistic alternate(s).

Numerators [numr]

This feature substitutes glyphs with their matching smaller alternates. The numerators are the same glyphs that are used to create fractions, their vertical position remains within the capital letters height. These glyphs are reduced in size and designed slightly heavier to keep them consistent with the rest of the font.

Denominators [dnom]

This feature substitutes glyphs with their matching smaller alternates and low position glyphs. The denominators are the same glyphs that are used to create fractions, their vertical position remains within the base line. These glyphs are reduced in size and designed slightly heavier to keep them consistent with the rest of the font.

Superscript / Superiors [sups]

This feature substitutes glyphs with their matching smaller alternates which are set slightly above the height of the capital letters. These glyphs are reduced in size and designed slightly heavier to keep them consistent with the rest of the font.

Subscript / Inferiors [subs]

This feature substitutes glyphs with their matching smaller alternates which are set slightly below the baseline. These glyphs are reduced in size and designed slightly heavier to keep them consistent with the rest of the font.

Standard Ligatures [liga]

Standard ligatures replaces a sequence of characters with a single ligature glyph, they are designed to improve kerning and readability of certain letter pairs.

Stylistics Set [ss01]

This feature replaces glyph(s) with stylistic alternate(s).

Stylistics Set 2 [ss02]

This feature replaces glyph(s) with stylistic alternate(s).

Stylistic Set 6 [ss06]

This feature activates alternate lowercase positioning of mathematical symbols.

Stylistic Set 7 [ss07]

This feature replaces glyph(s) with stylistic alternate(s).

Stylistic Set 20 [ss20]

This feature substitutes the letter “x” into the multiplication sign.
