# \includegraphics{*.pdf } substitutes in-figure symbols

I am using TeXstudio with its default settings. My figure is saved as PDF because I was unable to include *.eps because of the Unknown graphics extension: .eps-error. The figure opens without faults in Adobe Illustrator, however when I use \includegraphics{*.pdf }, the pi symbol on one of the axes of the figure is converted to the unequal symbol.

That looks pathetic!

How do I proceed to be able to include my figure correctly?
