Is there a way to retrieve the Arabic data that have been saved in the database in a different encoding?

Question

I had made a form to record attendance, I tried it on local server, Arabic data was saved in the database correctly and I could read it clearly, but When the form was published to public to enter their data, I was surprised that the data was saved in database like this ( حسام صديق ) so, my question is: Is there a way to display this data in a readable way?

i tried to change charset with connection like this mysqli_set_charset($conn,"utf8"); it goes from ( حسام صديق ) to ( ÙÂيصل محمد عبد الله علي)
