GS Character replacement
As the group separator, GS was used in the European Medicines Agency barcode after the 2012
London Olympics. Since GS characters are invisible in many text display tools, some areas need to
replace GS with characters that can be displayed. In other words, replace the 0x1D byte in the ASCII
code table with the displayable byte in ASCII.
Currently, the QR decoding module temporarily supports replacing GS with characters 0x20-0x7E in
ASCII.
The replacement method is as follows:
1) Read the setting code of "GS character replacement enable"
2) Read the setting code of "GS replacement character modification"
