Remarks
If the classifier fails to match a run-time character with a score that satisfies the classifier's accept threshold, the resulting CogOCRMaxChar.CharacterCode output is set to a special character code (0xF800) that means the character is "Unknown". This UnknownCharacterMarker provides an alias for displaying the unknown character code is the ResultString.
