UTF-8 Stumper

For some reason, I cannot get special characters to show up in browsers. When encoded as UTF-8. I’ve got PHP sending a UTF-8 header, XML encoding declaring UTF-8, and my MySQL database is set to en-utf-8. I’ve even put the hack in my .htaccess file described in https://unknowngenius.com/blog/archives/2004/08/14/helping-wordpress-deal-with-exotic-text-encoding/

I use UTF-8 for precise punctuation in my blog at https://ryancannon.com/ any suggestions?
