Problems converting Special characters from PDF to text

[Andreas Düster]

Hi, 

 

I am using PDFBox 1.7.0 (unofficial converted .net version from
http://pdfbox.lehmi.de/) to convert a pdf to text. 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!!
