Codabar, encodings for B and C are swapped #167

Hi!

Codabar_Code.Add('B', "1010010011");//"101011001011"); Codabar_Code.Add('C', "1001001011");//"110101100101");

I made a Codabar with the "Barcode Encoder" program included in BarcodeLib with the content "A3117013206375B". Then I read that with an Zebra TC52 device (built-in 2D code reader).

It outputs "A3117013206375C". Investigating this I found that the bit patterns for B and C has been swapped:

Codabar_Code.Add('B', "1010010011");//"101011001011"); Codabar_Code.Add('C', "1001001011");//"110101100101");

They should be: Codabar_Code.Add('B', "1001001011"); Codabar_Code.Add('C', "1010010011");

Uppercase B and C have been corrected, but lowercase has not fixed.

BarcodeStandard/Symbologies/Codabar.cs

Codabar_Code.Add('B', "1001001011");
Codabar_Code.Add('C', "1010010011");

Codabar_Code.Add('b', "1010010011");
Codabar_Code.Add('c', "1001001011");
