Text Encoding reading json file

[contato]

Hi there

This is the code to datasource read json file, it can contains these "áóãç" special caracters , i tried to encode with utf-8 but did not works, by the way it shows in page inside a template(i dont known if it matters)

 dataSource = new kendo.data.DataSource({
                transport: {
                    read: {
                        url: "data/file.json",
                        dataType: "json",
                        contentType: "application/json; charset=utf-8"
                    }
                }
            });

Thanks
