1,

   name = MimeUtility.encodeText(name,"UTF-8",null);

   name.replaceAll("\r", "").replaceAll("\n", "");

2

                name=newString(name.getBytes("UTF-8"),"ISO8859-1");// firefox浏览器

3

               name = java.net.URLEncoder.encode(name, "UTF-8");// IE浏览器

              name = name.replaceAll("\\+", "%20");

=====================

if (request.getHeader("User-Agent").toLowerCase().indexOf("firefox") > 0) {

name = new String(name.getBytes("UTF-8"), "ISO8859-1"); // firefox浏览器

} else if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") > 0) {

name = java.net.URLEncoder.encode(name, "UTF-8");// IE浏览器

name = name.replaceAll("\\+", "%20");

}else if (request.getHeader("User-Agent").toUpperCase().indexOf("CHROME") > 0) {

name = new String(name.getBytes("UTF-8"), "ISO8859-1");

}else {

name = new String(name.getBytes("UTF-8"), "ISO8859-1"); // firefox浏览器

}

=============================

response.setHeader("Content-disposition", "attachment;filename=\"" + fileName +"\"");
