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.

Replaces selected figures which follow a slash with denominator figures.

Replaces glyphs at the ends of words with alternate forms designed for this use. This is common in Latin connecting scripts, and required in various non-Latins like Arabic.

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

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

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