As already commented on stackoverflow to your crosspost there (http://stackoverflow.com/questions/14490829/itext-pdf-text-extraction-with-fonts-and-styles): mkl wrote > You already know the generic reasons (as addressed in Lee's answer) for > the difficulties of PDF text extraction from answers to your former > questions here.

The probably helping replacement in my last sentence there actually refers to situations in which: * the font as embedded in the PDF misses its to-unicode mapping, * you have the same font with that mapping, and * the mapping has not been mixed up in the embedding process. In that case it obviously suffices, BTW, to add your to-unicode mapping to the font in the PDF. There even is another situation in which font replacement might help: If some font replacement already took place before, i.e. if the font currently associated with the text in the PDF is not the font the PDF had originally been typeset with but some replacement (e.g. done for license reasons), replacing the font back to the original one may improve text parsing quality.
