How to decode POST response?

Question

Character encoding

Intercepted http requests on one site. A regular POST request is sent, and JSON is returned in response. In the browser program that monitors the requests, the response is displayed normally. But when I try to send a request manually, using Curl, I receive a text with an incomprehensible encoding in response.
