    Question conversion of pdf file to text using itext in java

    I have a problem while reading the content from pdf and creating a word document(doc/docx) in byte streams.Generated a word document contains junk characters instead of original text.

    Here is my code

     
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    import java.io.IOException;
     
    import com.itextpdf.text.pdf.PdfReader;
    import com.itextpdf.text.pdf.parser.ContentByteUtils;
    import com.lowagie.text.Document;
    import com.lowagie.text.DocumentException;
    import com.lowagie.text.Paragraph;
    import com.lowagie.text.rtf.RtfWriter2;
     
    public class Check1 {
     
     
     
     public static void main(String[] args) throws FileNotFoundException, IOException, DocumentException {
     
         PdfReader reader = new PdfReader("/home/mujafar/Desktop/NPTEL Transcription Guidelines.pdf");
            int n = reader.getNumberOfPages();
            System.out.println("total no of pages:::"+n);
     
             Document document = new Document();
     
             RtfWriter2.getInstance(document, new FileOutputStream("/home/mujafar/Desktop/file.docx"));
                System.out.println("file created");
                document.open();
                byte[] bytes;
                for(int i=1;i<=n;i++)
                {
     
                bytes= ContentByteUtils.getContentBytesForPage(reader, i);
     
                String s= new String(bytes);
                document.add(new Paragraph(s));
     
                document.newPage();
     
     
                }
     
                document.close();
     
     }

    Try isolating the problem. Is it on the input side or the output side?
    What is in the String s? Add a println(s) to see what is there.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks for reply. In itextpdf document.add() accepting "String" or "Element" datatype. Thats why i converted byte array to String (i.e 's'), and i passed the 's' to Document.add(new Paragraph(s)); But content in word document in junk characters instead of original text.Any help appreciated.
