    Default problem in reading the content from pdf and write in word document in java ?

    I have a problem while reading a content (text and images) from pdf file and write the content to word document. But content is junk characters in word document instead of original data. I have used itext-1.4.8.jar and itextpdf-5.0 jar . Any help appreciated.
    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();
        }
    }

    I have used itext-4.2.0.jar and itextpdf-5.4.5 jar and used com.lowagie.text.pdf.parser.PdfTextExtractor to read the pdf. Below is the attached piece of code which is working fine. I hope it helps

    package packJava;
     
    import java.io.FileNotFoundException;
    import java.io.FileWriter;
    import java.io.IOException;
    import java.io.PrintWriter; 
    import com.lowagie.text.DocumentException;
    import com.lowagie.text.pdf.PdfReader;
    import com.lowagie.text.pdf.parser.PdfTextExtractor;
     
    public class MainClass {
     
        public static void main(String[] args) throws FileNotFoundException,
                IOException, DocumentException { 
            PdfReader reader = new PdfReader(
                    "D:\\docs\\33745_The Immortals of Meluha - Chapter 1.pdf");
            int n = reader.getNumberOfPages();
            //System.out.println("total no of pages:::" + n);       
            PdfTextExtractor parser =new PdfTextExtractor(reader);       
            //System.out.println(parser.getTextFromPage(1));
            FileWriter write=new FileWriter("D:\\docs\\file4.doc",true);
            PrintWriter print_line= new PrintWriter(write);
            for(int i=1;i<n;i++){
            	print_line.printf("%s", parser.getTextFromPage(i));	
            }
            print_line.close();
            write.close();
        }
    }
