I did a presentation of a website in Illustrator with several art boards (pages) and saved as PDF.

Unfortunately I opened and saved it in Acrobat because I needed to change the default view size to 100% 72 dpi.

Now when I have to go back and open the PDF in Illustrator to make changes the characters in my PDF have become totally corrupted.

Also Illustrator dont get the artboard/multiple pages concept. It only want to open one page.

Guess the best solution is to stay away from PDF in the future and use Powerpoint or Keynote instead.

First i did a PDF with multiple pages (artboards) in Illustrator and saved as PDF.

Then I opened it in Acrobat and changed the view option for the PDF (to 72 DPI / 100%). Then save in Acrobat.

Then I needed to edit it again in Illustrator.

But when I open the PDF in illustrator (that have been saved in Acrobat) all text is corrupted. But it looks fine in Apple preview and Acrobat.

My problem is that the text looks like !#9D"% when opened in illustrator (but Acrobat renders it fine).

(Guess the artboard functionality got lost when I saved in Acrobat.)

Hi Luke,

I use Illutsrator CS6 and Acrobat 10.1.1. And I have checked that box on your screenshot.

But you solved one thing. The type that is messed up comes from a flowchart that was created in Powerpoint. I used Illustrator to clean it up and changed the fonts to Arial. The textblocks that was originally created in Powerpoint is the ones that are messed up.

This is how it went:

1. Flow chart created in Powerpoint and exported as PDF.

2. PDF is opened in Illustrator - everything looks nice.

3. I change some view settings in Acrobat and save.

4. Open the file again in Illustrator and it looks like ****.

Anyway, I have recreated the artwork.

But it's still a mystery for me why Acrobat and preview show it fine and Illustrator don't.
