Objective C, how to decode this UTF16 string?

Question

I have a string like this,

NSString *u = @"%u9ED1%u9AD4";

I need to decode this UTF16 string to obtain the unicode entity below:

黑體

I am trying this:

NSData *fontNameData = [@"%u9ED1%u9AD4" dataUsingEncoding:NSUTF16StringEncoding];
   NSString *l = [[NSString alloc] initWithData:fontNameData encoding:NSUTF16StringEncoding];
   NSLog (l);

Doesn't seem to work. What am I doing wrong? Will greatly appreciate the help

Like this:

NSString *u = @"%u9ED1%u9AD4";
u = [u stringByReplacingOccurrencesOfString:@"%u" withString:@"\\u"];
u = [u stringByApplyingTransform:@"Any-Hex" reverse:YES];
NSLog(@"%@", u); // 黑體
