Messaging : Support Emijo between Android and iOS

Question

I'm creating an app for to sending messages from one user to another user.

This app is developed in Android and iOS (swift 2.2).

In Android I'm using org.apache.commons to encode / decode string to Unicode using StringEscapeUtils.escapeJava and StringEscapeUtils.unescapeJava Encoding method gave me this result (for a string containing emojis) :

Hello \uD83E\uDD23

This is impossible to decode this in Swift.

According to this post, I think iOS need this String as input to correct decode it :

Hello \u{D83E}\u{DD23}

Is there an easy way to make iOS and Android compatible ?

Found solution :

static func decode(input: String) -> String? {
    let ns = NSString(string: input)
    let data:NSData = ns.dataUsingEncoding(NSUTF8StringEncoding)!

    return NSString(data:data,encoding:NSNonLossyASCIIStringEncoding) as? String
}
