>             Project: PDFBox
>          Issue Type: Bug

>            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}
