Problem with opening files and fonts

[Valerio27369308xugr]

Hi, I have a very serious problem with my Illustrator file: I can't open all the tables together of a pdf made with illustrator and also when I open single pages some characters are converted into strange writings like "#!@33#" and various. How can I fix? Thank you

And that PDF has been created in which app?

Excel? YOu might want to get rid of Calibri before exporting it from Excel.
