Encode Emoji to string

Question

I want to encode this emoji 😈 to string:

I have tried like this:

let data = self.comment.dataUsingEncoding(NSNonLossyASCIIStringEncoding, allowLossyConversion: true) if let data = data { let emojiString = NSString(data: data, encoding: NSUTF8StringEncoding) as! String self.comment = emojiString }

but it doesn't work.

I want to encode like 😈 , not \ud83d\ude08

So how to do this?

128520 is the unicode scalar value of "😈":

let text = "😈😀" let encoded = text.unicodeScalars.map { "&#" + String($0.value) + ";" }.joinWithSeparator("") print(encoded) // &#128520;&#128512;

This helps me. Thanks a lot @Martin R 😈.

it should be let unicode = text.unicodeScalars.map({ "&#" + String($0.value) }).joinWithSeparator(",") to get expected string :D

@Hoa: OP said: "I want to encode like 😈" and that is the syntax of XML "character entities". But anyway, it should be easy to adapt the example code to the concrete needs.
