any software? any technique? in C or any other language.

you might want to take a look at PDF2TXT. It is a simple tool (perl script) to extract text from PDF files.

Key Features:

.. Extract Japanese text - JIS, SJIS, EUC and UCS2 encoded strings from
  Japanese PDF files by use of CMap files.
.. Extract document information and bookmark.
.. Support decoding methods:
    ASCIIHexDecode, ASCII85Decode, FlateDecode, LZWDecode
.. Crypto (pdf2txt_X.XX) and non-crypto (pdf2txt_X.XX_no_crypto) version.

Requirements:           UNIX

.. Perl (>= 5.005_03)    CPAN
.. zlib        
.. Compress::Zlib        CPAN
.. uncompress            UNIX uncompress command
.. Jcode       
.. aj12.tar.Z  
.. aj20.tar.Z  

[+crypto version]
.. MD5                   CPAN

To get pdf2txt:

Here is another way to do the same.

PDF Conversion by E-mail

There are three e-mail options you can use to convert PDF
documents to a format that is more accessible to screen reading
software. The e-mail address you use depends on the conversion
format you want, plain (ASCII) text or HTML, and whether the
PDF is on the Internet or local media.

Option 1
If the PDF is on the Internet, you can mail the URL (web address)
of the PDF in the body of an email message to (for plain text) or to
(for HTML). The convertor will mail back the translation of the
PDF file. You can submit multiple URLs in a single e-mail.

Tip: Some URLs are very long and cumbersome to type. Cutting
and pasting the URL into the mail message will save you some

Option 2
If the PDF is on local media, such as a hard drive, CD-ROM, or
internal server, it can be submitted as a MIME attachment to an
e-mail message. All converted pdf-documents will be sent back
to the sender as MIME attachments. For plain text, mail the
attached PDF to For HTML, mail the
attached PDF to

Option 3

A service hosted by Trace Research Center also allows you to
convert PDF documents.

You can either mail the URL of the PDF or attach the PDF
document itself to your email message and send it to (for plain text) or to (for HTML). The convertor will
mail back the translation of the PDF file.

Adobe would like to thank Dr. Gregg Vanderheiden and the
Trace Research Center ( for helping us host
this service.

i tried all the email solutions. they all failed in the same place -- they converted 'Offer' to 'oxxxxer' whre xxxx is some funny character.

seems like that's the state of the art in pdf->txt conversion.

i would suggest that you post this problem to adobe and bring this to their notice. Who knows, this might be a known bug, due to version compability problem, or something!!

can't ask the author/creator of the doc. no special or international character in the problematic *words*. i did not read every word of the doc so can't say about the entire doc.
