Also, not sure about the gritty details on an PDF, but when I scan from a book and create an OCRed version of it, I have the option to place the "real text" that is used when you copy something out layered below the gaphical representation of the same text.

So, though the text looks like "damage" it could still be stored within the PDF as "da mage".

Also you could try different PDF Readers. I like foxit.

Also helping someitmes when copying data that is split within the pdf into separate blocks, just mark smaller parts before copying them out to get the correct order of the paragraphs and texts.
