// Returns a new string made from the receiver by replacing all characters not in the allowedCharacters set with percent encoded characters. UTF-8 encoding is used to determine the correct percent encoded characters. Entire URL strings cannot be percent-encoded. This method is intended to percent-encode an URL component or subcomponent string, NOT the entire URL string. Any characters in allowedCharacters outside of the 7-bit ASCII range are ignored.

// You can create/fetch any restorable objects associated with the user activity, and pass them to the restorationHandler. They will then have the UIResponder restoreUserActivityState: method
// invoked with the user activity. Invoking the restorationHandler is optional. It may be copied and invoked later, and it will bounce to the main thread to complete its work and call
