Wide character print even with utf8 encoding
<p>I am getting a <code>"Wide character in print"</code> warning even with encoding set to <code>utf8</code>:</p>

<pre><code>use WWW::Mechanize;
$mech = new WWW::Mechanize;
$mech-&gt;get("http://www.ilo.org/dyn/triblex/triblexmain.fullText?p_lang=en&amp;p_judgment_no=88&amp;p_language_code=FR");
$mech-&gt;save_content("output.html", binmode =&gt; ':encoding(UTF-8)');
</code></pre>

<p>What is the solution to this problem?</p>
