解决文件下载时文件名乱码问题

 在西安做项目时 遇到的一个文件下载 文件名乱码的问题 ，下面是解决方案：

 //输出文件流
       response.setContentType("application/octet-stream;charset=ISO8859-1");
   String agent = request.getHeader("USER-AGENT");
   if (null != agent && -1 != agent.indexOf("MSIE")){
    response.setHeader("Content-Disposition","attachment;" + "filename=" + URLEncoder.encode( file.getName() , "UTF8"));
   }
   else if (null != agent && -1 != agent.indexOf("Mozilla")){   
    response.setHeader("Content-Disposition","attachment;" + "filename=" + new String(file.getName().getBytes("UTF-8"),"ISO8859-1"));
   }
   else {
      response.setHeader("Content-Disposition","attachment;filename=" + file.getName() );
   }
       java.io.FileInputStream fr = new java.io.FileInputStream(fpath);
         java.io.InputStreamReader is = new java.io.InputStreamReader(fr,"ISO8859-1");  
         java.io.BufferedReader br=new java.io.BufferedReader(is);
   out = response.getOutputStream();
   
   int i = 0;
   while((i= br.read()) != -1){  
             out.write(i);
         }
