issue in file:
https://github.com/apache/incubator-airflow/blob/master/airflow/utils/email.py#L73
>>> mime_text = MIMEText(html_content, 'html')
The charset is not passed in and the default charset is "us-ascii"
The fix is to pass in the right charset base on html_context:
>>> mime_text = MIMEText(html_content, 'html’, “us-ascii" if
>>> isinstance(html_content, str) else "utf-8”)
