When the Page slug is in cyrillic and permalink is ON - 404 page not found

[kalifi]

Hello

1. On fresh install of the Wordpress 2.8 beta
   
2. Enable permalink - /%category%/%postname%
   
3. Create post with slug "тест" - then you can access it trough the link from the side bar and the URL contains "тест" at the end
   
4. Create Page with slug "страница" - the link "Страница" appears in the sidebar, but when you click it - 404 page not found, and the url is ​http://blogaddress/страница[[BR]]

The same bug exists in 2.7.1. I'm using MAMP with php 5 the permalinks are behaving normal when using just latin characters, the database is utf8_general_ci.

Hope you can fix this !
