如何让这段代码提交一个带有jQuery/Ajax工作的UTF-8表单textarea？

<form id="myForm">
 <textarea id="myTextarea" name="myTextarea"></textarea>
 <button type="submit">提交</button>
</form>

$(document).ready(function() {
  $('#myForm').submit(function(event) {
    event.preventDefault();
    var textareaContent = $('#myTextarea').val();
    $.ajax({
      url: 'your-server-url',
      type: 'POST',
      data: {
        content: textareaContent
      },
      contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
      success: function(response) {
        // 处理成功的响应
        console.log(response);
      },
      error: function(xhr, status, error) {
        // 处理错误响应
        console.error(error);
      }
    });
  });
});
