How to make urldecode in ajax request?

Question

JavaScript

I send a post request to the server with data in json format and Cyrillic turns into %25D0%25BF%25D1%2580
How to fix it?

$.ajax({
          type: "POST",
          url: '/saveObj/',
          contentType: 'application/json; charset=utf-8',
          data: JSON.stringify(arr),
          success: function(data)
          {
            // location.reload(true);
          }
        });

Encoding problem. With so little information, it's hard to say anything more specific.

Answer 3

Well you have already decided everything in the last question.
Why are you repeating?

in django do
print(request.POST)
