想实现下保存网页，试了下百度可以，打开来没有问题，但试了试url如果是www.google.com.hk，打开来就是乱码。。。不知道怎么解决
学java没多久。。新手求教。。
以下是java代码

public static void savePage(URL url) throws IOException, ParserException, IllegalArgumentException{
        InputStream is = url.openStream();
        int i;
        String title = HTMLHelper.getTitle(url);
        String file = url.getFile().trim();
        String host = url.getHost().trim();
        String filename = title+"("+url.getHost()+file+")";
        FileOutputStream fos = new FileOutputStream("Pages\\"+filename+".html");
        do{
            i = is.read();
            fos.write(i);
        }
        while(i!=-1);
        is.close();
        fos.close();
        System.out.println("Success!The filename is:"+filename+".html");

    }
