I have just upgraded my OJS to 3.2.0.3 but I realized that in the reference part after extracting the references and publishing it the non-English words automatically became to be as question mark like this ???.
Please see one example of references from here:

I thought that it might be from “theme” that is why I tried to change different themes but it didn’t work as well.
*There is no Error log messages in this regard.
It would be great to help me in this regard to find out why it is working like that.
Sincerely
Hourakhsh
