I'm parsing an RSS feed that has an ’ in it. SimpleXML turns this into a ’. What can I do to stop this?

Just to answer some of the questions that have come up - I'm pulling an RSS feed using CURL. If I output this directly to the browser, the ’ displays as ’ which is what's expected. When I create a new SimpleXMLElement using this, (e.g. $xml = new SimpleXmlElement($raw_feed); and dump the $xml variable, every instance of ’ is replaced with ’.

It appears that SimpleXML is having trouble with UTF-8 ampersand encoded characters. (The XML declaration specifies UTF-8.)

I do have control over the feed after CURL has retrieved the feed before it's used to construct a SimpleXML element.
