I ran into an issue this morning trying to deal with special characters in the RSS feed. I found that some characters were being escaped twice when using the cdata_wrap filter. An example is with a single apostrophe in article.name:

RSS Feed output:

<title><![CDATA[King to look &amp;#39;behind the curtain&amp;#39; at U.S. Supreme Court Justices&amp;#39; relationships]]></title>

Title Outputs with the ' because the ampersand was escaped a second time
King to look 'behind the curtain ' at U.S. Supreme Court Justices' relationships

I solved the issue for now by using inline cdata along with the filter escape_once. There might be a better answer, but for now I fixed with the following:

<title><![CDATA[{{ article.name | escape_once }}]]></title>
...
<description>{% if article.data.description != blank %}<![CDATA[{{ article.data.description | escape_once }}]]>{% else %}{% if article.content[rname] != blank %}<![CDATA[{{ article.content[rname] | select_html: css_selector: "p", limit: 1 | strip_html | escape_once }}]]>{% endif %}{% endif %}</description>
