Has it ever worked? If not, what did you change just before it started?
Have you added or removed any fonts lately?
Can you display the contents of Russian-language documents (not only PDF's)?
Can you view the page linked below?
Hello, i have the same problem and i checked the page bellow. I do not see how this page can help to resolve a problem if it discribes the funcion of apple police.app

(created via french windows, dowloaded via web outlook)
