Norwegian characters problem
<p>I create a folder as follows.</p>

<pre><code>function create(){
if ($this-&gt;input-&gt;post('name')){
    ...
            ...
    $folder = $this-&gt;input-&gt;post('name');
    $folder = strtolower($folder);
    $forbidden = array(" ", "å", "ø", "æ", "Å", "Ø", "Æ");
    $folder = str_replace($forbidden, "_", $folder);
    $folder = 'images/'.$folder;
    $this-&gt;_create_path($folder);
            ...
</code></pre>

<p>However it does not replace Norwegian character with _ (under bar)</p>

<p>For example, Åtest øre will create a folder called ã…test_ã¸re.</p>

<p>I have </p>

<pre><code>&lt;meta http-equiv="content-type" content="text/html; charset=utf-8" /&gt;
</code></pre>

<p>in a header. </p>

<p>I am using PHP/codeigniter on XAMPP/Windows Vista.</p>

<p>How can I solve this problem?</p>
