How do I escape a Unicode character in my 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

The proper escape sequence would be something along the lines of

wchar_t * str = L"\x0627";

See this question: http://stackoverflow.com/questions/755741/character-constant-000-xhh/755763

Edit: Oh, sorry, I missed the iPhone and Objective-C tags. The above is valid for generic C/C++, but I have not worked with iPhone development so your mileage may vary.

Answer 2

Example:

 NSString *stuff = @"The Greek letter Beta looks like this: \u03b2"

Answer 3

If you don't want to put it directly in your string you can use a format specifier like this:

[string stringByAppendingFormat:@"%C", 0x2665];
