I have been using PDFBox to extract text from several different PDF files fine. I use the latest PDFBox app with ExtractText class. There is one PDF that PDFBox (and iText) fails to extract any text even though I can extract the text with Adobe Reader and also pdftotext.exe part of XPdf. I don't want to have to rely on using pdftotext.exe from a PC since this is part of an automated application. I think the error relates to an unknown font type and having to use the few fonts installed in the jar file. I tried running the API classes and trying to force a font from a certain location but I still got errors. I thought I loaded the font with the loadTTF method but I don't know if that did anything with the font. I would really like to have this working straight from the ExtractText class anyway. I'm thinking I might have to build my own after putting a bunch of Windows fonts somewhere and changing a properties file but I really don't know if that is the right direction I should be taking and I am new to PDFBox. Any ideas? Here are the errors I am getting. I tried this from both a Windows PC and our system but I get the same errors. The section starting processEncodedText and on repeats a few times so I just included the first entries.
