when sql query has utf character in it, codeigniter doesn't execute query

I think I just found more practical way,
utf8_encode() function seems to do the trick no need to monkey around with file encoding.

example:
$sql = utf8_encode("select * from tbl_product where title='Сборная'");
$this->db->query($sql);
