EasyBlog SEO doesn't work with UNICODE (russian) titles of posts.

Hello! Dear friends, I have problem with unicode russian titles. I was made the posts, SEO was enabled in EasyBlog setting and standart Joomla SEF was enabled too. Post with english title works very fine. Post with russian title was translated in english by letters very nice, but this URL doesn't work (error 404). I tried enable and disable russian letters translation, but got no any positive effect. After that sh404SEF was installed for test, and I got working URLs. Can you help me? Thank you!

Jomla: 3.5.0 Stable (without any third-party frameworks, templates and hacks).
EasyBlog: latest (I was bought and downloaded it yesterday).
