Apostrophes getting converted to html entities

[eluser]Oblong[/eluser]
Hello.

I'm having trouble with form validation with data that includes an apostrophe - it gets converted to an html entity.

The validation I'm using:

Code:

$this->form_validation->set_rules('surname','Surname','required|trim|xss_clean|max_length[255]');

If, for example, I enter "O'Reilly" in that field, it shows up as

Code:

O'Reilly

in the DB.

Any advice appreciated.
