Tilman Hausherr updated PDFBOX-4076:
------------------------------------
Affects Version/s: 2.0.8
> PDFBox cannot properly handle PDF Name objects containing bytes with values
> outside the US_ASCII range
> ------------------------------------------------------------------------------------------------------
>
> Key: PDFBOX-4076
> URL: https://issues.apache.org/jira/browse/PDFBOX-4076
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.8
> Reporter: Tilman Hausherr
> Priority: Major
>
> As reported by ~mkl in SO answer
> {quote}The first error in PDF Name handling is that PDFBox internally
> represents them as strings after a mixed UTF-8 / CP-1252 decoding strategy.
> This is wrong, according to the PDF specification a name object is an atomic
> symbol uniquely defined by a sequence of any characters (8-bit values) except
> null (character code 0).
> (...)
> The second error is, though, that while serializing the PDF it only properly
> encodes the characters in the strings representing names which are from
> US_ASCII, all else are replaced by '?'{quote}
> sample code
> {code:java}
> PDDocument document = new PDDocument();
> PDPage page = new PDPage();
> document.addPage(page);
> document.getDocumentCatalog().getCOSObject().setString(COSName.getPDFName("äöüß"),
> "äöüß");
> ByteArrayOutputStream baos = new ByteArrayOutputStream();
> document.save(baos);
> document.close();
> document = PDDocument.load(baos.toByteArray());
> System.out.println(document.getDocumentCatalog().getCOSObject().keySet());
> document.close();
> {code}
> output:
> {noformat}
> [COSName{Type}, COSName{Version}, COSName{Pages}, COSName{????}]
> {noformat}
