When i open a PDF in Illustrator the characters become corrupted. It looks like "#D)9! etc.
Apples preview and Acrobat shows the text right. But when opened in illustrator everything is wrong. The font I use is plain Arial.
Illustrator is not a universal PDF editor. You can usually open a PDF that was created in Illustrator (with Illustrator editing capabilities) but a PDF created from any other program is a risky. What is it you are trying to do?
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.
Did you save the PDF with Illustrator compatibility?
You should, if you want to have the ability to edit the PDF later.
I don't get your point about opening single pages of a multiple page PDF in Illustrator. You might want to explain what exactly you did.
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.)
I just tried this in Illustrator 6 and Acrobat 10 and it worked fine. I suspect you used an earlier version of Acrobat that did not support multiple artboards? If you used the Illustrator default to save your PDF, the fonts should have been embedded and should not have changed after saving in Acrobat. You can check for embedded fonts in Acrobat (File> Properties> fonts). Did your file originate in Illustrator? PDFs from Powerpoint, and Publisher can be problematic, because of un-embedded fonts, even when placed in Illustrator.
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.
The problem comes from the Calibri font used in MS Office. It's the same with Excel when copy/pasting a chart from Excel to AI if the Calibri(Theme Body) font was used. You must make the change in PP before moving the file to AI.
