UTF-8 Problem

Hi...

I've got a silly problem. I'm using a MySQL 4.1 with UTF-8 charset.
phpMyAdmin with UTF-8 charset aswell. The problem is when I enter data
in phpMyAdmin or any other MySQL tool, I can't see non standard letter
in my app. But when I enter data in my app i can't see thos chars in
let's say phpMyAdmin. Notice that my app is UTF-8 aswell... Any ideas
what's wrong? (PHP 5.0.3)

TIA
