6.8 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”.
(3) The character replaced by GS is represented by two hexadecimal values, and the
corresponding hexadecimal conversion table of the character is shown in Appendix F
(4) Read the "Save" setting code:
