JsonResponse symfony how to use cyrillic?

Question

symfony

when I use return new JsonResponse($data);
in the latest version of symphony, instead of Cyrillic, I get \u041f\u0430\u0448\u0430
as well as escaping slashes.
How do I write JSON_UNESCAPED_UNICODE and JSON_UNESCAPED_SLASHES for JsonResponse in symfony?

Answer 1

In my opinion, there is only one constant that can be passed to setEncodingOptions

$response = new JsonResponse(['message' => 'Привет!']);
$response->setEncodingOptions(JSON_UNESCAPED_UNICODE);

return $response;

Answer 2

In this scenario, when there are slashes, Russian letters and tags, if not converted to UTF-8, I received
return new JsonResponse($data);

Malformed UTF-8 characters, possibly incorrectly encoded

So at least how I had to call like this

return new JsonResponse(mb_convert_encoding($data, 'UTF-8', 'UTF-8'));
