Convert Decimal NCRs Code into UTF-8 in java (JSP)

I was trying to decode string which in FARSI to UTF-8 but then i checked browser itself convert FARSI string into Decimal NCRs Code

How i can convert Decimal NCRs Code into UTF-8 ??

String farMsg = "عتباري";
String finalMsg = new String(farMsg.getBytes(),"UTF-8");
System.out.println("\n Farsi Message \n" + finalMsg);

when i am trying convert using above code it is working fine but if i am using same string from an input box of JSP page its is giving me some output like this

عتباري

What modification do I need to do for converting into same.

EDIT

I entered عتباري in the jsp input box and in used request.getParameter("faMSg") to get the value and here i got عتباري but i should get عتباري
