I thank again both Zeljko and Baptiste.
Meanwhile, I found out a more or less simple way of solving the problem:
1. edited the pdf file with Inkscape, inserting 0 or 1 over the rectangles;
2. saved the pdf file;
3. opened it with Acrobat Reader, and selected, as text, the 0 and 1 inserted;
4. pasted the 0 and 1 into a text editor.
And that was done!
