utf-8 - Swift 中的 NSJSONSerialization 和非拉丁(西里尔)字符

Question

这是我解析 JSON 的函数:

func jsonParsingWeather(urlPath:String) -> NSDictionary {
    var utf8URLPath = urlPath.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)
    println("URL path for JSON: \(utf8URLPath)")
    var streamData:NSData = NSData(contentsOfURL: NSURL(string: utf8URLPath))
    var error: NSError?
    var fullWeatherDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(streamData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary
    println("Full parsing array: \(fullWeatherDictionary)")
    return fullWeatherDictionary
}

在处理西里尔字符时发现问题

urlPath = http://autocomplete.wunderground.com/aq?query=Самара

utf8URLPath = http://autocomplete.wunderground.com/aq?query=%D0%A1%D0%B0%D0%BC%D0%B0%D1%80%D0%B0

在 Safari 浏览器中，两行给出相同的结果:{“结果”:[{“名称”:“Самара，Россия”，“类型”:“城市”，“c”:“RU”，“zmw”:“00000.1.28807”，“tz”: “欧洲/萨马拉”，“tzs”:“SAMT”，“l”:“/q/zmw:00000.1.28807”，“ll”:“53.250000 50.450001”，“lat”:“53.250000”，“lon”: “50.450001”}]}

但是!数组 fullWeatherDictionary 为空!

{
    RESULTS =     (
    );
}

为了比较，取一个拉丁字符串:

urlPath = http://autocomplete.wunderground.com/aq?query=Samara

utf8URLPath = http://autocomplete.wunderground.com/aq?query=Samara

在 Safari 浏览器中，两行给出相同的结果:{ "RESULTS": [ { "name": "Samara, Russia", "type": "city", "c": "RU", "zmw": "00000.1.28807", "tz": “欧洲/萨马拉”，“tzs”:“SAMT”，“l”:“/q/zmw:00000.1.28807”，“ll”:“53.250000 50.450001”，“lat”:“53.250000”，“lon”: "50.450001"}, { "name": "Samarate, Italy", "type": "city", "c": "IT", "zmw": "00000.101.16066", "tz": "欧洲/罗马", "tzs": "CEST", "l": "/q/zmw:00000.101.16066", "ll": "45.625370 8.783435", "lat": "45.625370", "lon": "8.783435"} ............

因此，数组 fullWeatherDictionary 是:

{
    RESULTS =     (
                {
            c = RU;
            l = "/q/zmw:00000.1.28807";
            lat = "53.250000";
            ll = "53.250000 50.450001";
            lon = "50.450001";
            name = "Samara, Russia";
            type = city;
            tz = "Europe/Samara";
            tzs = SAMT;
            zmw = "00000.1.28807";
        },
.......................

怎么了？为什么在非拉丁字符的情况下数组 fullWeatherDictionary 的内容不同？

网址 http://autocomplete.wunderground.com/aq?query=%D0%A1%D0%B0%D0%BC%D0%B0%D1%80%D0%B0还在 Safari 中给出空结果。

这是服务器问题。
