答

仍然不清楚如何提交数据， answer在上述模拟问题中提供。

It's still not clear how you submit the data but the answer is available in the mentioned simliar question.

在PDF 2.0之前，标准提交操作的字符集不能由PDF规范指定/调整，并且读者应用程序可以选择任何适当的字符集。

The charset for a standard submit action is not specified/adjustable by the PDF specification until PDF 2.0 and the reader application may choose any appropriate charset.

使用JavaScript操作以特定字符集而不是提交操作提交表单数据：

Use a JavaScript action to submit the form data with a specific charset instead of a submit action:

submitForm({
    cURL: "https://www.example.com/your-script.php",
    cSubmitAs: "HTML",
    cCharset: 'utf-8'
});
