Substituting text font in Acrobat 9.0
I have a PDF that came to us, from a different typesetter. We need to edit, and do not have the fonts used. We need to make these edits, before the book goes out. I get the following error "The change to a different font was not done because the chosen font and the font encodings in the document differ and could not be resolved". Could you please help me resolve this. We would like to substitute a different (similar) font with the few edits. Thank you very kindly in advanced in helping me out.
