MatchChar method is an abstract method that derived display character classes implement. This method returns a value indicating whether the specified character matches this display character. If this method returns False for a character, the user can not enter that character in the place of this display character.
Note: Typically you don't need to use this method directly as the XamMaskedInput will automatically validate the user input against the specified mask.
