The first thing you need to do is to modify your php. Note: You can subsequently use phpinfo to verify that this has been set properly. While this change will ensure that PHP always outputs UTF-8 as the character encoding in browser response Content-type headers , you still need to make a number of modifications to your PHP code to make sure that it properly processes and generates UTF-8 characters.

Moodle will not install if you have large format enabled without the Barracuda file format. This in conjunction with the row format being either "Compressed" or "Dynamic" allows for large varchar indexes above characters.
