我正在阅读一个csv文件，并使用下面的代码将其作为JSON写入MongoDB

bucket_name = "my-bucket"
    file_name = "input.csv"
    csv_data = pd.DataFrame(pd.read_csv('gs://' + bucket_name + '/' + file_name, encoding='utf-8'))
    csv_data = csv_data.to_dict(orient="records")
    db.task.insert_many(csv_data)

下面是输入csv文件

ID,Name,Identity,Alignment,EyeColor,HairColor,Gender,Status,Appearances,FirstAppearance,Year,Universe

100004,Mogul (Earth-616),,,,Bald,,Living,,îàé-70,1970,DC

它有一些不是Unicode的字符。有没有办法
1.我可以用类似“invalid”的字符替换这些无效字符，并继续处理并存储在mongo数据库中。
1.有没有办法把它放在数据库里？
我得到的错误
