not properly display Cyrillic names joomla users

[pipp]

Hi!
I have installed the latest version of DHTMLX Scheduler for Joomla.
But I was faced with incorrect display of the user name in Russian.
Database joomla (2.5) encoded UTF-8.
So is displayed in the admin panel and frontend.
Please help to fix the problem.
Thank
