i dont have acrobat pro version. added attachement thank you Zitat von Olaf Drümmer <[email protected]>:
If the text encoding or ToUnicode table for that character does not make the connection to the right Unicode value - then it can't be extracted properly.There are two quick ways to double check:- use a recent version of Adobe Reader or Adobe Acrobat, copy the piece of text in question and paste it into a Unicode enabled text window or control - try text extraction with PDFlib TET (cf. http://www.pdflib.com/download/tet/ )If neither of these get the right Unicode values, you are probably out of luck. If they are showing the right character, report back.You could also use a low level inspection tool (for example in Acrobat Pro, use Preflight and from the Preflight window's options menu choose "Explore PDF structure") and drill down to the resp. font resource and find out whether it has a decent ToUnicode entry or not.Olaf ---Olaf Druemmer | Managing Director | callas software GmbH | Schoenhauser Allee 6/7 | 10119 Berlin Tel +49.30.4439031-0 | Fax +49.30.4416402 | [email protected] | www.callassoftware.com?

It works fine for me except one thing. My Problem is that the pdf contains gaussian brackets which are converted to a single letter (right ceil is converted to a "d" and left floor one to a "c". I need at least something unique because I want parse the text later and I need to localize the brackets. I am not sure if thats a problem of PDF box at all. If I copy the bracket out of the pdf manually it?s the same behavior. Any idea to help me?Thanks!!
