使用response.setHeader("Content-Disposition","attachment;filename="+fName)下载文件，中文文件名无法显示

 这是部分代码
 response.setContentType("application/msword");
 String uncod= URLDecoder.decode(fileName);
 fileName = new String(uncod.getBytes("UTF-8"), "UTF-8");
 response.setHeader("Content-Disposition", "attachment;filename=".concat(String.valueOf(fileName)));
这样写中文会丢失

改成如下

fileName = new String(uncod.getBytes(), "ISO-8859-1");
便可解决
