Base64 encode from name for email
<p>Why does the opencart <a href="https://github.com/opencart/opencart/blob/master/upload/system/library/mail.php" rel="nofollow">mail class</a> encode the senders name?</p>

<pre><code>$header .= 'From: ' . '=?UTF-8?B?' . base64_encode($this-&gt;sender) . '?=' . '&lt;' . $this-&gt;from . '&gt;' . $this-&gt;newline;
</code></pre>

<p>Is this an old technique? I haven't seen it like this before.</p>

<p>Are there any disadvantages to encoding it? </p>
