title: How do I escape a Unicode character in my Objective-C source code?
body: <p>I feel incredibly stupid for asking this, but the documentation and Google are giving me no love at all.</p>
  
  <p>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? </p>
