Which function encodes accentuated letters in PHP?
<p>There is a MySQL database and I want to select columns from a table. </p>

<p>I must return a <code>String</code> from the <code>concatenation</code> of the selected column values. But in one of the columns there are <code>accentuated</code> letters in the column value , like <code>é</code>.</p>

<p>So how to encode the column returned value ? </p>

<p><strong>NB :</strong> I already wrote <code>header('Content-Type: text/plain; charset=utf-8');</code> at the beginning of the PHP file.</p>
