View source for Tips not in cyrillic

Hi there!
I have a little problem with Tips Not in Cyrillic.
There are tip on word Profile (screenshot – http://www.picshare.ru/view/10121173/ ). This tip I see not in cyrillic charset CP1251 and it's not readable.
The same charset (Western?) i see on page Whats New (with action whatsnew) when hover over hour of change (screenshot – http://www.picshare.ru/view/10121181/ ).
In /lang/wacko.ru.php all definitions written in CP1251 as well as
'RevisionTip' => 'Просмотреть историю изменений страницы',
Why I get this mess and where to fix it ?
