JAVA 读取 BiliBili 网页乱码。

public class Test1 {
    public static void main(String[] args) throws IOException {
        InputStream inputStream = new URL("http://www.bilibili.com/video/av6300269/").openStream();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "utf-8"));
        for (String s; (s = bufferedReader.readLine()) != null; ) {
            System.out.println(s);
        }
    }
}

我运行后显示乱码，请问问题出在哪里，你们也是这样吗?
