Hello,

When I read the barcode in the datamatrix GS-1 format below with the barcode reader, 0108680831020716211057301119091610160919 notepade prints this data.

There is an ascii code that does not appear in this data, but I cannot catch it while reading it from textbox. In what way can I see this hidden character.

hidden character = 123-0x7B

I'm trying to understand how this is a C# question, or a .NET Framework question.
 
How do you debug your decoder? Are you using an emulator?
Maybe try changing the format of your reader/writer :
new Barcode/Read/Writer { Format = BarcodeFormat.YOURFORMAT HERE }
 
This is gs1 datamatrix format, so as (21) in gs1 is serial number and serial can be 1 to 20 digit.

Hence they add a “FNC1” code after “105730” so that able to know which is the last digit of the serial number

This code is invisible to user and yet readable by code so that programmer can parse the serial number

This link explain the GS1 (AI), so 21 is serial number

This link let you check your 2D Code is it gs1 datamatrix
