要确保写入CSV文件的内容都是UTF-8编码的，使用`utf-8-sig`编码格式来打开文件并写入数据。修改代码如下：

filename = "ershoufang.csv"
with open(filename, "w", newline="", encoding='utf-8-sig') as f:
    data = [
        "id", "小区名称", "所在区域", "总价", "单价",
        "房屋户型", "所在楼层", "建筑面积", "户型结构",
        "套内面积", "建筑类型", "房屋朝向", "建筑结构",
        "装修情况", "梯户比例", "配备电梯", "产权年限",
        "挂牌时间", "交易权属", "上次交易", "房屋用途",
        "房屋年限", "产权所属", "抵押信息", "房本备件",
    ]
    writer = csv.writer(f, dialect='excel')
    writer.writerow(data)

# ...

filename = "ershoufang.csv"
with open(filename, "a", newline="", encoding='utf-8-sig') as f:
    writer = csv.writer(f, dialect='excel')
    writer.writerow(data)

在打开文件时，将`encoding`参数设置为`utf-8-sig`，这样可以确保写入CSV文件的内容以UTF-8编码格式保存。

请注意，写入CSV文件之前，确保`data`是一个包含正确数据的列表，以保证写入的数据格式正确。
