I have the same problem as "dcaunce". Certain .pdf documents print and view just fine, but if I try to copy/paste or save as text I just get garbage (mostly small squares). It is not a font problem. Some documents are OK, and some are not. All documents from one specific source have this problem, and that indicates to me that this might have to do with the way the .pdf is created?
