Feature: Character Class Escapes | regexp-features

^{Home | Features | Improve this section}

A Character Class Escape is a single character escape that represents an entire character class. They can be used as an element of a Character Class or as an Atom. It is often the case that a lower-case escape character is the inclusive set, while an upper-case variant of the same character excludes that set.
