Switching a web site to UTF-8

I'd enjoy a web site that had zero issues with characters rendered improperly, so I'm considering converting my web sites to use the UTF-8 character set for storage and presentation.

Steps

1. Convert all the existing data in every text field of every table in the database.
2. Convert all the html pages to declare UTF-8 as their encoding.
3. Convert all php scripts to use UTF-8 as the default character set.
4. Convert all mysql connections and requests to use UTF-8.
