The bug is in libitext-java (iText 2.1.7) and affects only the 1.41+dfsg-* versions of pdftk.
libitext-java changes the metada of the output pdf file (which is forced by its license). It includes the text "modified using iText 2.1.7 [...]" into the producer field. The metadata in a pdf file can additionally be saved in XMP (Extensible Metadata Platform). OpenOffice seems to add XMP by default, Libreoffice only if it is asked (e.g. by using PDF/A-1a output). Both write the normal metadata using UTF-16. libitext-java converts the metadata to UTF-8 but does not delete the UTF-16 BOM which leads only to a wrong displayed producer entry if there is no XMP data, but to a fail in the XML writer code with XMP. ** Also affects: libitext-java (Ubuntu) Importance: Undecided Status: New ** Changed in: pdftk (Ubuntu) Status: Confirmed => Fix Released ** Changed in: pdftk (Ubuntu) Assignee: (unassigned) => Johann Felix Soden (johfel) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/807409 Title: open office pdf has invalid characters To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libitext-java/+bug/807409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
