Private notes entered in Russian are displayed as ?????

I like to post private notes on films. I enter them in Russian, they are added OK, and displayed well. But once I reload the page they are displayed as ???????

Can I solve this problem?

Please post the Russian text here so I can investigate.

for example like this "это отличный фильм!"

This issue occurs only in private notes. Once I posted a review in Russian and it is displayed OK even after page reloading

They should work now

Thank you! It rocks!
