Defines the restricted recognition characters, so called characters blacklist, that are not allowed to recognize during subsequent OCR processes. The recognition is disabled for the provided characters, that means the engine doesn't consider the specified characters when processing.

For example, if you want to disable/not recognize the characters "0X@", set this parameter to "0X@".
