Bengali OCR not working properly

[Shubham Agrahari]

I am trying  to convert bengali pdf to text . I am using tessaract 4.0.0 for it . I have also downloaded the "ben traindata" from here -->  https://github.com/tesseract-ocr/tessdata/blob/master/ben.traineddata  but it is not working properly. It is not getting converted to text properly. Any suggestions would be highly appreciated.
