Barcode Info - Need Help

Hi,
 
I generate barcode using code 128; my values are listed bellow,
 
             <barcode>
                    <description>Code 128</description>
                    <msg>(J)JD01 2012 3456 0123 4560</msg>
                    <code128/>
             </barcode>
 
             <barcode>
                    <description>Code 128-1</description>
                    <msg>(2L)ES08820+40BRUA</msg>
                    <code128/>
             </barcode>
 
Problem is when reading this back form Barcode Reader it generate
different out put as
 
Code 128 result:            )J=JD01 2012 3456 0123 4560
Code 128-1 result:          )2L=ES08820`40BRUA
