json php output?

Question

PHP

I'm taking out now

die(json_encode(['error' => ['code' => 100, 'message' => 'Метод не задан.']]));

As a result I get:

{"error":{"code":100,"message":"\u041c\u0435\u0442\u043e\u0434 \u043d\u0435 \u0437\u0430\u0434\u0430\u043d."}}

How can I make the message display normally?
Added this:

header('Content-Type: application/json');
header('Accept: application/json');

the situation has not changed

Answer 1

json_encode(['error' => ['code' => 100, 'message' => 'Метод не задан.']], JSON_UNESCAPED_UNICODE );
