Error inserting special characters (spanish) into database

It´s not altered because I do this ...

Code:

$s = "INSERT INTO faqs_faqs(idfaq,title,question) VALUES ('','¿¿title??','¿¿cuestión??')";
$result = $this->db->query($s);
die;

In deed I did it too:

Code:

@mysql_query("USE prueba_borrar;INSERT INTO prueba(id,texto) VALUES ('','¿¿¿¿¿¿¿¿¿')");
die;
