Neil McErlean updated PDFBOX-1011:
----------------------------------
Attachment: testcase.patch
> Incorrect metadata for encrypted PDFs with non-ASCII characters
> ---------------------------------------------------------------
>
> Key: PDFBOX-1011
> URL: https://issues.apache.org/jira/browse/PDFBOX-1011
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 1.5.0
> Environment: I'm on Mac OS X 10.6, but I would think it affects all.
> Reporter: Neil McErlean
> Priority: Minor
> Attachments: MHH_Torque_convertor2.pdf, testcase.patch
>

> I have a document which has Author metadata = "Jırg Boettger". That second
> character is not an 'i', it is a dotless lower case i.
> It is also an encrypted pdf, with user password = "".
> The problem is that if I load the document, decrypt it and then try to
> examine the document-level metadata (such as author) I see problems with the
> non-ASCII chars.
> I will attach a testcase & the sample PDF that reproduces the problem for me.
> A bit of detail that may be useful: COSObject 19 0 at the end of the PDF
> defines the Author. It is represented as byte[] = {-95, -118, -50, 122, -127,
> 105, 53, 105, 50, 14, -27, 122, 120}
> SecurityHandler.encryptData() line 223 - which decrypts the string gives:
> J?rg Boettger. bytes = [74, -102, 114, 103, 32, 66, 111, 101, 116, 116, 103,
> 101, 114]
> Note the -102 in the second character.
> The second character, whose byte-value is -102 is not a displayable ASCII
> char (even at 256 -102 = 154) and it just gets dropped from the COSString &
> so we get an author of Jrg Boettger from PDDocumentInformation.
