/**
 * A Java 8 compliant Charset implementation for reading properties files.  It first tries
 * to load the properties file using UTF-8 encoding and if it encounters an error, tries to
 * load the file using ISO-8859-1 encoding.
 *
 * This class is only necessary because {@code sun.util.PropertyResourceBundleCharset} is not
 * available in Java 8.  This class can be removed in favor of {@code sun.util.PropertyResourceBundleCharset}

JSON互換のデータのみを受信するデータベース`fase_db`があるとしましょう。

例えば、`datetime`オブジェクトはJSONと互換性がないので、このデーターベースには受け取られません。

そのため、`datetime`オブジェクトは<a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO形式</a>のデータを含む`str`に変換されなければなりません。

同様に、このデータベースはPydanticモデル（属性を持つオブジェクト）を受け取らず、`dict`だけを受け取ります。

そのために`jsonable_encoder`を使用することができます。

Pydanticモデルのようなオブジェクトを受け取り、JSON互換版を返します:

```Python hl_lines="5 22"

                    }
                }
            }
        """

        file("res", nonAsciiFileName) << "foo"

        when:
        executer.withDefaultCharacterEncoding("ISO-8859-1").withTasks("copyFiles")
        executer.run()

        then:
        file("build/resources", nonAsciiFileName).exists()
    }

    @Issue("https://issues.gradle.org/browse/GRADLE-2181")

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no formato  <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.

Você pode usar a função `jsonable_encoder` para resolver isso.
