Dashes are punctuation marks that are commonly used in written text. A long dash (—) is known as an em dash, whereas a short dash (–) is known as an en dash. This plugin converts any whitespace around dashes into smaller hairspaces, to produce a more elegant typographic effect. Both em and en dashes are recognized. Look at the following sentence, which uses dashes: I love this plugin — and everything about it — because it works so well. When this plugin is activated, the sentence would appear like this (with smaller spaces around the dashes): I love this plugin?—?and everything about it?—?because it works so well.
