I'm trying to convert emoji to unicode characters. I tried using the second option suggested in this solution: iOS 5: How to convert an Emoji to a unicode character? but my output in my tableviewcell label just looks like this: \ud83d\ude0b Here's the code from saving the comment:

NSData *dataString = [body dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *goodValue = [[NSString alloc] initWithData:dataString encoding:NSUTF8StringEncoding];
NSDictionary *parameters = @{ @"body" : goodValue };
//and so forth it is saved to the cloud

And here's the conversion back to emoji:

NSData *data = [self.comment.body dataUsingEncoding:NSNonLossyASCIIStringEncoding];
NSString *goodValue = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
self.bodyLabel.text = goodValue;

Is `NSDictionary *parameters = @{ @"body" :body };` and `self.bodyLabel.text = self.comment.body;` doesn't work? – Cy-4AH May 14 '15 at 15:36
No they work they just output the \sdfsdlfjsdf stuff – smith938584 May 14 '15 at 15:37
In the first bit of code, what is `body` and where did it come from? – rmaddy May 14 '15 at 15:38
If it output `\sdfsdlfjsdf` then in body you have `\sdfsdlfjsdf` instead emojis. – Cy-4AH May 14 '15 at 15:42
body is self.commentTextView.textView.text – smith938584 May 14 '15 at 15:43
Then what's the point of the conversion? You have a string from the text view already. If you want a string for the label, why go through the seemingly pointless conversion to/from data? – rmaddy May 14 '15 at 15:54
Because in my label i want to see the emoji, so I'm attempting to convert it back, but it isnt working – smith938584 May 14 '15 at 16:03

Don't convert back and forward. Just assign. – Cy-4AH May 14 '15 at 16:14
Why don't you simply do `someLabel.text = someTextView.text;`? There is no reason (that you have explained anyway) why you need some strange conversion. – rmaddy May 15 '15 at 01:49
Add the unicode character you want by copy/past like: because \ud83d\ude0b is invalid. – zaph May 15 '15 at 03:23
