Status/update including HTML entities on post


So, I’m using Twitter API 1.1’s status/update to send a tweet. The problem is, when I have a special character, such as an apostrophe in the tweet string i.e:
$vinedesc = “News Reporter’s reaction”;
$connection->post(‘statuses/update’, array(‘status’ => $vinedesc));

The tweet is tweeting with HTML entities included i.e:

News Reporter's reaction

How can I stop this from happening?
