数据库中的UTF8字符无法在浏览器中正确显示 - MySQL和PHP CodeIgniter_course

<div class="post-text" itemprop="text"> <p>My database and tables are set to <code>utf8_general_ci</code> collation and <code>utf8</code> charset. CodeIgniter is set to <code>utf8</code>.

It's only breaking in the production machine, which is Ubuntu 11.10 64bit in AWS EC2. Static content from the <code>.php</code> files show up correctly, only the data coming from the database are messed up. Example page: <a href="http://dev.uzlist.com/browse/cat/nkv" rel="nofollow">http://dev.uzlist.com/browse/cat/nkv</a></p> <p>Any ideas why?</p> <p>Thanks.</p> <p><strong>FYI</strong>: When I do <code>error_log()</code> the data coming from the database, it's the same values I'm seeing on the page.
