Installing Moodle 2.2

I continue my experiments with Open Source LMS
Today i installed Moodle 2.2
The installation was easy . I get the only problem

unicode

must be installed and enabled

It is required that you store all your data in Unicode format (UTF-8). New installations must be performed into databases that have their default character set as Unicode. If you are upgrading, you should perform the UTF-8 migration process (see the Admin page).

To solve this problem i had  to change encoding of the database.

My database name is moodle_2.2.  

I have executed SQL command

ALTER DATABASE `moodle_2.2` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci

And now Moodle installation can be completed.
