When I am parsing HttpServletRequest to get form data using ServletFileUpload class.
I'm unable to get special characters as it's posted in Form data.
Sample Code:
List<FileItem> fileItemList = null;
ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory());
try {
fileItemList = upload.parseRequest(req);
} catch (FileUploadException e) {
e.printStackTrace();
}
if (!isEmpty(fileItemList)) {
for (FileItem fileItem : fileItemList) {
if (fileItem.isFormField()) {
System.out.println("Key: "+fileItem.getFieldName()+" :: Value: "+ fileItem.getString());
}
}
Form input text: “I’m coming up with a music band titled ‘Lalisom – The Lal Effect’, with Ratheesh Vega
Those special characters are not returning as it's, instead of it's show some un-identified symbols.
Have tried the below solutions, nothing worked out:

Is there any advice on how to fix it. Thanks in advance.
Note:- Issue occurs only when form post with binary upload.
