when i open the converted txt file in browser it is displayed correct.
is there a way to convert the character in pdf to unicode in txt?
like
text U+2308 text
Zitat von [email protected]:
thanks for the advice. I tried copying the character to notepad++
and its the same behavior. If i use pdflib i get blanket squares
for the special characters.
the characters are these:

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.

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!!
