/**
* What follows is a very special case where "\," is within the mask field of a line in a .hcmask file only because otherwise (without the "\")
* it would be interpreted as a custom charset definition.
*
* We need to replace all "\," with just "," within the mask (but allow the special case "\\," which means "\" followed by ",")
* Note: "\\" is not needed to replace all "\" within the mask! The meaning of "\\" within a line containing the string "\\," is just to allow "\" followed by ","
