I have a simple canvas app that utilizes the Barcode Scanner to read a barcode and save the value to a Sharepoint text field. Some datamatrix barcodes, when scanned, recognize a special character at the beginning of the barcode that saves to the Sharepoint list. Upon copying and pasting the barcode string into Notepad++, the character is shows as "GS" which apparently translates to Group Separator. This behavior is only exhibited when scanning the barcode on Android devices. iOS devices seem to ignore this character when scanning using the camera.
Problem is when trying to scan that barcode on other screens to lookup the item. On Android it displays a network error, on iOS it simply doesn't find the record.
How can I configure the barcode scanner to ignore the GS special character (or maybe it's called a control character?)?
