One dimensional barcode Code39, I checked the baidu, begins with a *, ends with a *, I checked the Internet bar code automatically generated, choose type of Code39, but some of the generated code contains *, some does not contain, parse out, is not included *; But if I hand in character with *, before and after the barcode cannot resolve, who can explain to me, the correct Code 39, does it include *, why some do not contain *? How can contain *?
