/**
* Display the post content for the feed.
*
* For encoding the HTML or the $encode_html parameter, there are three possible values:
* - '0' will make urls footnotes and use make_url_footnote().
* - '1' will encode special characters and automatically display all of the content.
* - '2' will strip all HTML tags from the content.
*
* Also note that you cannot set the amount of words and not set the HTML encoding.
* If that is the case, then the HTML encoding will default to 2, which will strip
* all HTML tags.
*
* To restrict the amount of words of the content, you can use the cut parameter.
* If the content is less than the amount, then there won't be any dots added to the end.
* If there is content left over, then dots will be added and the rest of the content
* will be removed.
