Answer 1

The tranformation            String stringValue = "abc\u5639\u563b";
            byte[] valueInUTF8 = stringValue.getBytes("UTF-8");
            stringValue = new String(valueInUTF8, "UTF-8");            
does nothing except use up memory and CPU cycles. The original content of 'stringValue' is UNICODE characters. The updated 'stringValue' will contain exactly the same characters as the old 'stringValue'.
