> It's possible that positionX is smaller than previous character's positionX.
> Current PDFTextStripper will not add space and extract them to one word.
> Added a patch to compare positionX < previous positionX case which can insert 
> a space.
> Disabled by default.
> Tested with 10002 PDF files which had the negative positionX issue. The 
> result was improved for all of them.
