NSJSONSerialization serialization of a string containing forward slashes / and HTML is escaped incorrectly

Question

I am trying to convert some simple HTML into a string value in a JSON object and I\'m having trouble getting the string encoding to not escape the string in NSJSONSerializat

Here's my subclass of AFJSONRequestSerializer to remove \ before / symbols in resulting JSON; handy if you use AFNetworking

class SanitizedAFJSONRequestSerializer: AFJSONRequestSerializer
{
    override func requestBySerializingRequest(request: NSURLRequest!, withParameters parameters: AnyObject!, error: NSErrorPointer) -> NSURLRequest!
    {
        var request = super.requestBySerializingRequest(request, withParameters: parameters, error: error)

        if let jsonData = request.HTTPBody
        {
            if let jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding) as? String
            {
                let sanitizedString = jsonString.stringByReplacingOccurrencesOfString("\\/", withString: "/", options: NSStringCompareOptions.CaseInsensitiveSearch, range:nil) as NSString

                println("sanitized json string: \(sanitizedString)")

                var mutableRequest = request.mutableCopy() as! NSMutableURLRequest
                mutableRequest.HTTPBody = sanitizedString.dataUsingEncoding(NSUTF8StringEncoding)
                request = mutableRequest
            }
        }

        return request
    }
}
