header data in python requests.put() does not change

Question

req2 = requests.put(url, json = json_data, headers= header)
print(req2.status_code)
print(req2.headers)

Where json_data = req1.json()

url = 'some url'

and

header = {'Content-Type': 'application/data;charset=UTF-16'}

In above code req1 gets a response from a server.
req1 json is passed with url to fetch response req2. I want to make req2 using PUT() with charset = utf-16. When I am trying to do this by setting headers of req2 (1st line of code) it doesn't do anything as still the statement print(req2.headers) prints

{'Date': 'Thu, 01 Mar 2018 09:51:00 GMT', 'Transfer-Encoding': 'chunked', 'Content-Type': 'application/json;charset=UTF-8'}

If I'm correct, req2.headers shows the response headers. You are setting the Content-Type of your request header, showing that the content you are sending is encoded in UTF-16. I don't think the response must have the same encoding as the request, it is up to the server to decide.

You should use the Accept-Charset header to say what content type you wish to receive:

Accept-Charset: utf-8

The server can still ignore you. Usually it's not a problem as Requests will decode the response for you if you use the response.text field.
