iphone - How do I escape a Unicode character in my Objective-C source code?

Question

I feel incredibly stupid for asking this, but the documentation and Google are giving me no love at all.

I have a Unicode character I want to insert into a string literal in the source code of my iPhone app. I know its hex value. What is the proper escape sequence to use? And for that matter, what obvious source of information am I overlooking that would have told me this?

Answer 1

Example:

NSString *stuff = @"The Greek letter Beta looks like this: u03b2, and the emoji for books looks like this: U0001F4DA";
