Laravel: Setting UTF-8 by default on response()->json()

The api must return special characters as "ñ". But I'm facing right now that the Laravel facade response()->json() does not return this characters by default.

Laravel: Cant set JSON utf-8 charset

How can I without changing every line, can response json always with this encoding.

middlewares, providers, some global handler, overriding methods?

Maybe if the header Accept-Charset is set to 'utf-8'

I'm looking for the best solution
