If I understand what you're asking, it all depends on how the pdf is 
made. For most pdf's, the text is actually text (ASCII  or equivalent 
characters) and can be selected. There are some pdf's however, where 
what looks like text is actually an image of some text (what you get if 
someone scans in a page of text). You can't select that "text" because 
its really an image, you need to use OCR software to turn it into 
actual text.

Hope that isn't too confusing.
