[PDFBOX-5213] PDFTextStripper adds next line symbol after sup values (regression)

• Type: Bug

Description

Since version 2.0.22

PDFTextStripper adds next line symbol after sup values.

Like earlier

"Other (12) 1,505 832"

Now:

"Other (12)
1,505 832"

 

You can see this by comparing files GS-2010-q4-earnings.pdf_expected.html (2.0.21 and earlier) and GS-2010-q4-earnings.pdf_result.html (2.0.22 and higher)

 

If I took latest version of PDFbox like 2.0.24 and copy code of PDFTextStripper from 2.0.21 and use it then I don't see this issue. So it's regression only in PDFTextStripper.

 

To reproduce, you can use next simple code (copied from your examples). pageBytes is file GS-2010-q4-earnings.pdf

List<String> pages = new ArrayList<>();

PDDocument pdDocument = null;
try {
String pass = "";
PDFParser parser = new PDFParser(new RandomAccessReadBuffer(pageBytes), pass);
pdDocument = parser.parse();

int numberOfPages = pdDocument.getNumberOfPages();
if (limit < numberOfPages)

{ numberOfPages = limit; }

// //

for (int i = 0; i < numberOfPages; i++)

{ PDFTextStripper stripper = new PDFTextStripper(); stripper.setStartPage(i + 1); stripper.setEndPage(i + 1); pages.add(stripper.getText(pdDocument)); }

} catch (Exception e)

{ log.error(e.getMessage(), e);  }

finally {
if (pdDocument != null)

{ try

{ pdDocument.close(); }

catch (IOException e) { log.error(e.getMessage(), e);  }

}
}
