--------------------------+-----------------------------
 Special characters like `&` in URLs should be encoded in HTML pages (`&`
 becomes `&`).

 Wordpress' oEmbed discovery in `WP_oEmbed::discover()` does not decode the
 encoded entities and then tries to fetch URLs like

     http://example.org/oembed.php?format=json&url=...

 It should use `htmlentities_decode()` on the extracted URLs.
