用于cyrlic数据的MySQL DB UnicodeEncodeError的SQLAlchemy插入

我在MySQL数据库中使用Python.SQLAlchemy。 所有代码都适用于数据中的拉丁符号，但不适用于西里尔语：

UnicodeEncodeError:“charmap”编解码器无法在中编码字符 位置0-17：角色映射到

我在引擎构造函数中添加了encoding='utf8'，convert_unicode=True，但没有什么可更改的

MySQL中表utf8/utf8-bin的字符集/排序规则

代码：

我能做什么

尝试将？charset=utf8mb4添加到连接URI的末尾。是的，它可以工作？字符集=utf8mb4，Gord Thompson，Reagrds！尝试将？charset=utf8mb4添加到连接URI的末尾。是的，它可以工作？字符集=utf8mb4，Gord Thompson，Reagrds！
