@Vandersteen I think it is correct behavior because Code128 automatically switch between the three subsets (A, B, and C) to code the data in the shortest form.
And if subset C is picked, a leading "0" is added if there are an odd number of digits in the code as you also found.

Specifying Code128B specifically solved the issue for me.

Thanks for reporting, I'm investigating the issue.

It appears to be happening when having an 'uneven' number of numbers:

Generates a correct barcode:

  • 1234
  • 123456
  • 12345678

Generates a barcode prefixed with 0:

  • 123
  • 12345
  • 1234567

Which appears to be coming from:

//CODE C: adds a 0 to the front of the Data if the length is not divisible by 2

I don't have knowledge of the CODE128 barcode structure so this might be correct behaviour
