2. how do i do it?

thank you all for your answers.

Answer 1

if you put this line in your controller constructor it forces everything to be utf-8

class Article extends CI_Controller {

  function __construct() {

    parent::__construct();

    // set all to utf-8 
    $this->output->set_header('Content-Type: text/html; charset=utf-8');

  } 

// controller methods etc 

the links will be output in your view files -- this insures that all your text including links will be output in utf-8 encoding. the other side of this is characters that are not allowed in the url by default by codeigniter -- in application/config/config.php check out

$config['permitted_uri_chars']
