Hello,
The below doc should help you get started with scan handlers
ScanHandler: removing a GS, FS, RS from a barcode
you will want to use the Replace(R) function instead of the Remove(X)
example:
A(0)[R\\1DYOURCHARACTER]
NOTE: the character you want to use may not work because it is a character with in the expression itself..if that is the case you may want to write a script.
