At least once, but it's been a while. From the top of my head: - set encoding at HTML head - also at any HTML form element - Set database collation correctly - I believe it also needs to be done per table - The PHP -> MySQL connection itself may need to have the encoding set - All string manipulation to be done with mb_ - Even ensure your code files themselves are in UTF8
