Auto detecting urls inside text - urls have some arabic letters

You need to URL encode the tag to get it to work with auto_link. It looks like this works, at least for this simple example.

Code:

$this->load->helper('url');
$url = "https://soundeals.com/community/tag/";
$tag = "ميكروفون";
echo urldecode(auto_link($url . urlencode($tag)));

i have the following code please focus :

PHP Code:

$text = "an article text is just like this and we are inside the body of the article and there is a url inside the text with some arabic letters like this one

https://soundeals.com/community/tag/ميكروفون

i tried to use the auto_url to get the urls converted to < a >tags but it fails as folloing";

echo auto_link($text); 


i do not have a url in a variable i have it inside a text !!
