pass a variable to controller (with nonenglish characters)

[eluser]chejnik[/eluser]
Hello, thank you.

I have encoded the url with urlencode - the result is here

Code:

..search/showHeadword/sei n % C 3 % B E roska/0

I devided the urlencoded word with spaces, because it is formatted.

Code:

$string1 = urlencode($item["keyword"]);
            
        $segments = array('search', 'showHeadword', $string1, $item["num_keyword"]);
        $url = site_url($segments);

But when I click on the link / this message shows - The URI you submitted has disallowed characters.
Thank you Ales
