Getting error message while Installing Moodle 2.0
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).
Solution:
1. Open your Moodle database which you created in MySQL using phpMyAdmin
2. Run
ALTER DATABASE mydatabasename charset=utf8;
MyDataBaseName= Your Moodle database
3. No more error message saying
