iOS 5: How to convert an Emoji to a unicode character?

Question

I want to convert an Emoji to a unicode character in iOS 5.

For example, converting to \ue415.

I went to NSStringEncoding in NSString Class Reference.

In iOS 4, NSUTF16BigEndianStringEncoding and NSUTF32BigEndianStringEncoding gave me <e415> and <0000e415>, respectively, which are quite close to what I want.

In iOS 5, the results are different. It gaves <d83dde04> and <0001f604>.

How can I get \ue415 for in iOS 5? Thank you.

   NSData *data = [strEmo dataUsingEncoding:NSNonLossyASCIIStringEncoding];
   NSString *goodValue = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
   

2. Very easy to convert unicode to Emoji
