While I'm copying some text from a pdf in Preview and pasting it to MS Word, all the text is getting replaced either by blank space or by " ��� ����". what I'm supposed to retain the text? Plz help.

I know there are different types of PDF files, see / read the link I added in my post.

If you have missed it : TYPES OF PDFS: NATIVE VS. SCANNED PDFS

But you don't seem to know that there are Native PDFs which cannot be copy/pasted or searched. You can pretend that these are Scanned pdfs and use an OCR app to convert them to Word format, but that is not selective and the result may well need a lot of editing. I guess the OP can decide whether this process makes sense for his particular needs. Ideally the publisher should use another process to produced his Native pdfs which does not use a junk text encoding.

Try a different font.

Does this happen with all pdf's or only with pdf's from this particular source? The copyright holder might have disabled the copying of text and other content.
