[Zint-barcode] Possible MaxiCode encoding error

[Ed D. <ede...@gm...>]

Hi,

I am a c/C++ developer, I am new to Zint. I have been using the Zint
backend library (version 2.4.3 cloned from
git://git.code.sf.net/p/zint/code zint-code). I am producing MaxiCode
symbols, but I have come across what seems to be an error when
encoding some specific data in a MaxiCode symbol. I can reproduce the
symptom in Zint BarCode studio 2.4. I am encoding the following data
in Mode 4.

When I encode the data: "MaxiCode
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"
(without the quotes), and scan the symbol my scanner, a Honeywell
4600g, I get "MaxiCode
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz160826066,".

The data returned by the scanner matches the input except for the last
9 bytes. I have observed that if I shorten the data by removing the
last character(the zero), the data returned matches the input.

I was able to successfully encode, and scan the data above with the
ByteScout encoder available from:
http://bytescout.com/files/BarCodeGenerator.exe

I have attached .png file (ZintMaxiCode.png) generated by Zint BarCode
Studio (which does not scan properly), and a .png file generated by
ByteScout's BarCodeGenerator which I have scanned properly.

Has anyone seen this issue before? Is there a fix available? Perhaps I
have exceeded some limit. I haven't been able to find a post, but like
I said I am new to Zint...

Thanks for any help!
