HttpURLConnection 字符编码

Question

我正在制作一个简单的程序。使用字符集 "utf-8" 有一个 url。我想从此页面获取全部资源，但是存在字符编码问题。

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

class WholeTest {

    HttpURLConnection conn;


    public void openUrl() throws Exception {

        URL pageUrl = new URL("http://naver.com");
        conn = (HttpURLConnection)pageUrl.openConnection();
        conn.setRequestMethod("GET");
        conn.setUseCaches(false);

        conn.setRequestProperty("Host", "naver.com");
        conn.setRequestProperty("Connection", "keep-alive");
        conn.setRequestProperty("Cache-Control", "max-age=0");
        conn.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
        conn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36");
        conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");
        conn.setRequestProperty("Accept-Language", "ko-KR,ko;q=0.8,en-US;q=0.6,en;q=0.4");


        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(),"utf-8"));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        System.out.println("---result---");
        System.out.println(response.toString());
    }
}


public class Whole {

    public static void main(String args[]) throws Exception {
        System.out.print("Test");

        WholeTest w = new WholeTest();
        w.openUrl();
    }

}

结果是：？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？我无法查看源代码。我在读取inputStream时使用了字符集"utf-8"，我做错了什么？

我用的都是utf-8, UTF-8, euc-kr, EUC-KR ... 同样的结果。

正如我怀疑的那样，评论或删除下面的行。它会像一个魅力。

conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");

当 return 实际上是 text/html

时，您期待 gzip 二进制文件
