Getting a web page to display your content as TRUE utf-8 requires everything to be set at the utf-8 encoding. 'Everything' includes: your database, your database tables, your database fields, your connection from php to your database, you header as set by php, your header as set by html, your content itself etc.
The following resources were extremely helpful to me when I was switching to utf-8 (which is by far the better encoding over ISO):
http://www.phpwact.org/php/i18n/utf-8
http://www.phpwact.org/php/i18n/utf-8/mysql
Bonus tip: make sure your content and files are saved as utf-8 without BOM (Byte Order Mark), this will save you lots of trouble later!
