String filename=villagename+ "-" +poorname+ ". Doc";
Response.setcontenttype ("Application/doc");
Final String useragent = Request.getheader ("user-agent");
if (Stringutils.contains (useragent, "MSIE")) {//ie browser
filename = urlencoder.encode (filename, "UTF-8");
}else if (Stringutils.contains (useragent, "Mozilla")) {//google, Firefox browser
filename = new String (Filename.getbytes (), "iso8859-1");
}else{
filename = urlencoder.encode (filename, "UTF-8");//Other browsers
