FontFeature.stylisticAlternates constructor

const FontFeature.stylisticAlternates()

Enable stylistic alternates. (salt)

Some fonts have alternative forms that are not tied to a particular purpose (such as being historical forms, or contextually relevant alternatives, or ligatures, etc). This font feature enables these purely stylistic alternatives.

This may override other features that substitute glyphs.

The Source Code Pro font supports the salt feature. It causes some glyphs to be rendered differently, for example the "a" and "g" glyphs change from their typographically common double-storey forms to simpler single-storey forms, the dollar sign's line changes from discontinuous to continuous (and is angled), and the "0" rendering changes from a center dot to a slash.
