Junk characters C40 with C++ API IDAutomation_DMFontEncode


We're calling the IDAutomation_DMFontEncode function in IDAutomationDataMatrix.h with these parameters:
· DataToEncode: "000000000000000000000001000012345600010003000"
· ProcessTilde: false
· EncodingMode: 1 (E_C40)
· PreferredFormat: 0

The function returns this string:
APFIELHLBIHOHKAOFLHOAMDK
APPLBIHOHCAMPPFAPKGOKIKK
AIHOHCAOMPFENGAKEAAKJIBK
ADEFJPFIPABGEIOLBKMIPHNK
AMEAMJCIOCPLBLEGEBJMPJJK
AOAEOIOGCCAKIOEAIOMGMCEK

When we put the result in the IDAutomationDMatrix font and scan, it shows this data:
000000000000000000000001000012345600010003000GRJHR251

The characters "GRJHR251" at the end are erroneous. They do not appear in any other encoding mode other than C40.
Our IDAutomationDataMatrix.h header says "C++ Header File for IDAutomation Data Matrix Fonts V2020".
Note that we are not using a DLL or library of any kind. We were supplied the files IDAutomationDataMatrix.h and IDAutomationDataMatrix.cpp and we compile them into our application. Is there any update to the C++ code which fixes this?

Operating System: Windows 10

Application: Custom application using the C++ code in IDAutomationDataMatrix.cpp.

Thank you for informing us of this issue, we will make note of it and update it in the next release. However, at this time another release is not planned this year. The 2020 version is the latest version of the C++ file. We recommend using another encoding, such as ASCII until then if that can work in your application.
