> ok, I looked at it some more and I'd like to have you get the latest nightly
> build and try to run ExtractText on your original PDF again. If it doesn't
> work then run the ExtractFonts again(using the nightly build) and post the
> results.
> The issue is that there is some extra data at the end of the Cmap stream and
> tonight I happened to fix an issue with parsing and having extra data at the
> end of the stream for a different user. So I don't know if this is the same
> issue but I'd rather have you try the nightly build than have me chasing a
> ghost.

> shoot, I think your document was encrypted. It needs to be decrypted for the

> Attached is a simple java program that will create a new pseudo PDF document
> that contains just the Font information. Please run it on the problem PDF
> and upload the resulting CmapDocument.pdf
> It is a simple command line program, first compile then run it like this
> java ExtractFonts my.pdf
> Let me know if you have any questions getting it running.

> Hi Matt,
> Can you try one for me first; upgrade to the latest nightly build of PDFBox(
> http://www.pdfbox.org/dist/ ) and see if this is still an issue. There have
> been some changes to the CMAPParser.
> If it is still an issue I think we can write a simple program to extract just
> the fonts from your PDF and that should be enough for me to fix the bug.
