Special characters are the characters the engine will use when replacing all missing or rejected characters. This helps finding the missing or rejected characters with minimal effort when the recognition results are saved to a file.

To update the special characters, call the L_Doc2SetSpecialChar / L_Doc2SetSpecialCharExt function.

To recognize one or more pages, call the L_Doc2Recognize / L_Doc2RecognizeExt function.
