Russian language shows incorrect

[allahverdi]

I got a problem.
I have 2 documents: test.php and index2.php . In test.php it gets data from MySQL db. Data is in Russian. Test.php shows correctly it. But, when i include it to index2.php it shows incorrect.
In test.php there is nothing, just it get's from mysql. There is no doctype, content-type and etc.
But in index2.php there are all. My charset is UTF-8 which shows Russian normally in other places.

Here are both of them:
test.php

index2.php

Thanks a lot...
