NSCharacterSet - append another character set

NSCharacterSet - append another character set

I would like to create a character set that includes all of its own
characters, as well as those from another character set. Append in other
words.
I thought there'd be an obvious way, but after control-space completion in
the IDE, and then poking around the docs, I couldn't fine anything. How do
I do this?
