I just want to point to something useful for WordPress users who embed code and get burned by WordPress rewriting single-quotes.
One solution to the problem is to embed the following code into your functions.php page.
So far it looks like it’s working. I may have some earlier posts that are still a problem but given the massive volume this site is getting at the moment I’ll take my chances on it.
And credit where credit is due, this is where I found the answer, much thanks!
