Month name not translating to russian

Dear all, I have a website whose dates are not translating to russian, instead of the month-name I get a strange character output:

This is what I see in the front end in Russian instead of a month-name:

‘
<h2>??????</h2>
‘

The code I use to generate this is:
‘
<?php the_time(‘F’) ?>
‘
In english they show correctly, but not in russian language.

Can you pls advice on how to overcome this situation?
I have added all the language russian files to /languages folder on wp-content
