How to save the new pages in Cyrillic?

[Samuil]

Hi!
Thanks for good CMS getsimple. I try create and save any pages in Russian but the I see next message "Error: You cannot save a page with an empty title or slug."

getsimple doesn't see Russian title and Russian pages. Also I don't see any Russian pages in path /getsimple/data/pages/

All pages of English content work very good.

Please help me. How I can create site with Russian pages?
