CharacterSet

extension CharacterSet

`

                afURLQueryAllowed
                `

Creates a CharacterSet from RFC 3986 allowed characters.

RFC 3986 states that the following characters are “reserved” characters.

• General Delimiters: “:”, “#”, “[”, “]”, “@”, “?”, “/”
• Sub-Delimiters: “!”, “$”, “&”, “‘”, “(”, “)”, “*”, “+”, “,”, “;”, “=”

In RFC 3986 - Section 3.4, it states that the “?” and “/” characters should not be escaped to allow query strings to include a URL. Therefore, all “reserved” characters with the exception of “?” and “/” should be percent-escaped in the query string.
