weird characters in the url

i got your point osci.

i may confuse you with my previews posts.

I will explain my technique for search form and pagination. I'll keep it short

i have a controller and a method index in it. In the index i fetch a db table and pass it to a view with pagination also

Code:

class Welcome extends CI_Controller {
    
   function index($search_terms = '')
   {

        //  retrieve data
        //  configure the pagination
        //  load the view
   }
}

In the view i have also a search form that when i submit it , it goes to a pre-search method tha produces the query string, When the query is ready i redirect to the index and pass to it the query string . Please notice in the code above i have

Code:

function index($search_terms = '')

The var $search_terms i pass it to the model where i can have $this->db->like('name',$search_terms);

Code:

function pre_search()
   {
        
        //  retrieve submited data from $_POST
        //  generate the query string in this format: $keyword = search_by_name=Doe+John
        //  and pass it to the view
        redirect('index/'.$keyword);
   }

The procedure above has as a result to produce a url like that

Code:

http://test.loc/welcome/index/search_by_name=Doe+John

and that's how i accomplish search results with pagination.

The problem is when i search with a greek keyword

Code:

search_by_name=τεστ

the $search_terms var contains hex value like that

Code:

search_by_name = CF84CEB5CF83CF84

so the sql query fails to return any value.


I hope you understand what i wrote , my english aren't so good.

Do you suggest a different method to achive search results with pagination?
