使用编码UTF-8

参考技术A 显示的也是UTF8字符，若原本是汉字，需要转换到UNIcode或GBK字符才能正常显示

HttpURLConnection 接收网络数据出现乱码问题

由于接收的数据经过gZip处理过，所以在接受的时候也要处理，并且加上编码格式（没有会出现部分数据乱码）：

具体代码实现如下：

URL ul = new URL(url);
HttpURLConnection conn = (HttpURLConnection) ul.openConnection();
conn.connect();
InputStream in = conn.getInputStream();

StringBuffer sb = new StringBuffer();
String readLine = new String();
GZIPInputStream gZipS=new GZIPInputStream(in);
InputStreamReader res = new InputStreamReader(gZipS,"UTF-8");
BufferedReader responseReader = new BufferedReader(res);
while ((readLine = responseReader.readLine()) != null) {
	sb.append(readLine);
}
responseReader.close();

 测试问题解决。。
