multipart/form-data server don't read right single quote

[softDeveloper]

Hi, I'm submitting a html file in a form enctype=multipart/form-data file item to the server:

at the server:

 <%@ page language="java" contentType="text/html; charset=utf-8"%><meta http-equiv="Content-Type" content="text/html; charset=utf-8">

DiskFileUpload fu = new DiskFileUpload();
fu.setSizeMax(5000000);
List fileItems = fu.parseRequest(request);
Iterator itr = fileItems.iterator();

while(itr.hasNext()) {
  FileItem fi = (FileItem)itr.next();
  if(!fi.isFormField()) {

    text=fi.getString();
 }

the problem is it can't read some characters like right single quotes.

Wouldn't and hadn't turn Wouldnt and hadnt.

Regards
