Spaces are ignored when reading a PDF file

[Hesham G.]

Hello ,

I have a PDF file created using Latex. I am trying to read and print all 
letters in that file using PDFBox, but when doing this all spaces in that file 
are ignored. Here is the code I am using:
PDPage page = (PDPage)allPages.get( 0 );
PDStream contents = page.getContents();
if ( contents != null ) {
    PDFTextStripperProcessor pdfTextStripperProcessor = new 
PDFTextStripperProcessor();
    pdfTextStripperProcessor.processStream( page, page.findResources(), 
contents.getStream() );
}

public class PDFTextStripperProcessor extends PDFTextStripper {
    @Override
    public void processTextPosition( TextPosition text )  {
        System.out.println( text.getCharacter() );
    }
}

And you can check a one page file sample here to test it:

What is the cause of this issue please?


Best regards ,
