Json result

Hi everyone,

I'm integrating with a bank in Brazil to register payment slips, and it's returning a JSON with the following information. How can I change the text to correct accents and Portuguese (Brazil) characters? Thank you.

{"type":"https://developers.c6bank.com.br/v1/err ... quisição inválida.","status":400,"detail":"[BoletoClient]: Erro ao inserir registro: Já existe o título 10201374 com o seu número TESTE002 cadastrado . Bad Request","correlation_id":"9f25b39d97dc1b26-GRU","timestamp":"2026-04-26T12:48:27.169Z"}
