pdftools just extracts the textual data in the file and stores it in
Text instances - it doesn't try to interpret or decode the text. I'd
like to fix the library so that it does try and decode the text
properly and put it into unicode strings, but I don't have the time
right now.

Remember that text can be stored in PDF files in many different
ways, and that the text cannot always be extracted in its original
form.

You need to do something like this:

f = open("myfilename", "w").write("".join (text))

Don't worry about it. It's much better than my Spanish will ever be.

Sorry I couldn't give you more help with this. You may find that the
other tools mentioned by people in this thread will do what you
need better than pdftools can at the moment.
