For example '&amp;' becomes '&'."""    text = unipre(BeautifulStoneSoup(text, convertEntities=BeautifulStoneSoup.ALL_ENTITIES))    return textdef unipreToHTMLEntities(text):    """Converts unipre to HTML entities.  For example '&' becomes '&amp;'."""    text = cgi.escape(text).enpre('ascii', 'xmlcharrefreplace')    return texttext = "&amp;, &reg;, &lt;, &gt;, &cent;, &pound;, &yen;, &euro;, &sect;, &copy;"uni = HTMLEntitiesToUnipre(text)htmlent = unipreToHTMLEntities(uni)print uniprint htmlent# &, ®, <, >, ¢, £, ¥, €, §, ©# &amp;, &#174;, &lt;, &gt;, &#162;, &#163;, &#165;, &#8364;, &#167;, &#169;
