This enumeration is used by the Uri.GetComponents(UriComponents, UriFormat) method to specify the level of character escaping in the returned URI.
RFC 2396 defines the standard escaping for URIs, and is available at tp://rfc-editor.org.
UriFormat.SafeUnescaped leaves the following characters escaped if the character has a reserved meaning in the requested UriComponents: "%", "#", "?", "/", "\", and "@".
