I'm having a problem with a pdf file my teacher gave me. When I open the file, some of the characters appear as small boxes and question marks, while all the others are right. The funny thing is that none of my classmates is having trouble with viewing the file.
I assumed it was a font problem, but then again when I looked at the file properties all the fonts were embedded.
I use Windows XP SP3 and the teacher uses a Mac. Could this be of any relevance? Any ideas to where might the problem be coming from?
Your teacher needs to embed the fonts used into the pdf file.
