    OCR is used when the entire page is an image. Otherwise, we extract the text from the PDF page. It's possible that the font encoding of your PDF is bad and that's why you are seeing the results you are getting.  Can you share the PDF in question?

    Sure I will Post My PDF. And I am using ExtractTextTableInfoWithTableStructureFromPdf.java I saw on DeveloperLive Video They said APIs are using OCR and Aodbe Sensei for increase more Accuracy. So i Run the code for extract text from PDF(image) and PDF(Not Image) Then Can you answer me Am i Right?? 
    APIs Are using only when the PDF File is Image and If PDF is not image APIs aren't use OCR??

    And he PDF file is in Korean, but the API recognizes it in English. So that's the reason text is □H�Q!
