Escaping the trademark symbol with MySQL

I know this is probably me just being over-scrupulous, but is there really any need for this?

Code:

$query = $this->db->update('prj_docsections',&$ds); // <-- dereferencing $ds

I've also noticed this with a few other variables, such as the $data variable you're passing into the view. In theory this shouldn't have any impact, but you never know...

Just out of interest. What happens when you store update the database without first encoding the input?

I doubt this is the cause of your problem, but you never know. Failing that, I think it must be an encoding issue as Colin suggested.
