I have a piece of code in Python 3 that retrieves information from a website :

webpage = urllib.request.urlopen('http://www.bdm.insee.fr/bdm2/index.action')
webpage = webpage.read()
webpage = webpage.decode("ISO-8859-1")
parser = etree.HTMLParser()
tree = etree.fromstring(webpage,parser)
for liste in tree.iterfind(".//ul"):
   print(etree.tostring(liste, pretty_print=True).decode("utf-8"))

I don't understand why some characters are rightly encoded while others aren't. Here is a portion of the output :

<ul class="liens"><li><a href="http://www.insee.fr/fr/publications-et-services/default.asp?page=rediffusion/rediffusion-abon-bdm.htm">Souscription</a></li>
</ul>
<ul id="lienstransversauxbas"><li class="premier" id="navigation-lettre">&#13;
<a href="http://www.insee.fr/fr/publications-et-services/default.asp?page=abonnements/liste-abonnements.htm" title="Lire la lettre d'information">Lettre d'information</a>&#13;
</li>&#13;
<li id="navigation-plan">&#13;
<a accesskey="3" href="http://www.insee.fr/fr/publications-et-services/services/plan-du-site.asp" title="Plan du site">Plan du site</a>&#13;
</li>&#13;
<li id="navigation-boutique">&#13;
<a href="http://www.webcommerce.insee.fr/index.php" title="Acc&#233;der &#224; la boutique en ligne">Acheter les publications</a>&#13;
</li>&#13;
<li id="navigation-credits">&#13;
<a accesskey="8" href="http://www.insee.fr/fr/publications-et-services/default.asp?page=copyright.htm" title="Copyright Insee">Mentions l&#233;gales et cr&#233;dits</a>&#13;
</li>&#13;
</ul>

What are those &#13?

Thanks,

Michael

那些是回车。我怀疑etree是明确包括它们以便保留空白，就像使用&nbsp;来保留空间一样。不过，这是一个猜测；我没有&#13;在原始来源中看到，所以我不清楚为什么etree要竭尽全力保护它。
