i have a problem with copying text from english pdf to a word file. the english text of pdf turns to be unknown signs when i copy them to word file .
i illustrated what i mean in the picture i attached . note that i have adobe acrobat reader 9 . so please help cause i need to copy text to translate it .
Is this an e-book? Does it allow for copying? It is possible that the pdf file is a scan of a book?
