Enable ensure_ascii in custom jsonb encoder

[FyZzyss]

Hello.
I'm trying to write to a json field with ascii characters. This does not work even with ensure_ascii=False The encoding in the database is utf-8, so it's not about it. How to fix it?

My code:

    @staticmethod
    def _encode_jsonb(value: Union[Dict, List]) -> str:
        return json.dumps(value, default=str, ensure_ascii=False)

    @staticmethod
    def _decode_jsonb(value: str) -> Union[Dict, List]:
        return json.loads(value)

    async def _init_connection(self, conn: asyncpg.Connection) -> None:
        await conn.set_type_codec(
            'jsonb',
            encoder=self._encode_jsonb,
            decoder=self._decode_jsonb,
            schema='pg_catalog',
        )

Can you elaborate on how exactly it "does not work" please?

The data is displayed correctly in all logs. After writing to the database, incorrect text in jsonb field is obtained:
{"error_id": null, "code": 1, "text": "\u0422\u0430\u0439\u043c\u0430\u0443\u0442 \u0441\u043e\u043e\u0431\u0449\u0435\u043d\u0438\u044f \u0432 \u043e\u0447\u0435\u0440\u0435\u0434\u0438", "type": "timeout"}
