Now Tesseract OCR needs "osd.traineddata" OCR dictionary by default because the default value of OcrEngineSettings.RecognitionRegionType property is changed from RecognitionRegionType.RecognizeSingleBlock to RecognitionRegionType.RecognizePageWithPageSegmentationAndOrientationDetection. This change allowed to improve quality of text recognition result.
