iACS emulation - Enhance character codepage for non-printable character and allow for substitution

This is a request to enhance the character code page/table for non-printable characters in the 5250 emulator.

Character code page should follow GS1 General Specifications standards for these characters and allow for substitution to a readable character such as a dash, tilde, pipe, or any other suitable character.

There are three different separator characters used within the data matrix string that should be considered:
record separator (ASCII 29)
group separator (ASCII 30)
end of transaction (ASCII 4)

Full ASCII table available at link below. First column shows all non-printable characters that could be added into character table for substitution:

Use Case:

Scanning a barcode with GS- Group Separators does not read the group separators and simply drops them from the data stream. This makes parsing barcode data without a fixed length impossible. Passing the non-printable characters through the emulator via character substitution would allow for the data to be parsed by programs.

    Thank you for submitting a Request For Enhancement. This request would require modifications to the data stream. That is not something we would consider doing. For that reason, we are declining this request.
