The Code 128C font must be an even number of digits. This is by design.
There is a 1: 1 mapping between numbers and the resulting output, and the output is 2-bit. In case 1 , the 128C code representation of that number is 01
if the value was 12 , then the base view would be 12
therefore, the numbers 628 can only be represented by 0628
The wikipedia article on Code 128 explains the differences between 128A, 128B, and 128C encodings.
