unichar and NSString - how interchangeable are these?

Question

There is an NSString method -characterAtIndex: which returns an unichar.

• (unichar)characterAtIndex:(NSUInteger)index

Answer 1

Another option is to use the class method:

+ (id)stringWithCharacters:(const unichar *)characters length:(NSUInteger)length;

So just using:

yourString = [NSString stringWithCharacters: &yourChar length: 1];

The yourChar parameter must be a pointer.
