How can I decode ajax request's response?

Question

I'm using Telegram web version. Here is a screenshot of it:

As you see in the image above, all ajax requests' responses are made of vague characters. I mean the response contains unknown characters. For example I've received Text3 as a new comment, but I cannot see it (the word o Test3 ) in the ajax response. I've tested all responses, all of them look the same.

Anyway, do you know how can I decode it? I mean how can I convert them to English characters?

Answer 1

Try checking the response headers for the content encoding or the Content-Type. That may help in figuring out the encoding used by the server.
