New issue 4283: UTF8MB4 issue with MySQL 8 and PyMySQL
https://bitbucket.org/zzzeek/sqlalchemy/issues/4283/utf8mb4-issue-with-mysql-8-and-pymysql

colafly:

Using MySQL 8 and PyMySQL 0.8.1 with SQLAlchemy 1.2.8.

```
e = create_engine('mysql+pymysql://account@localhost:3306/db?charset=utf8mb4')
e.connect()

~/lib/python3.6/site-packages/pymysql/cursors.py:170: Warning: (3719, "'utf8' is currently an alias for the character set UTF8MB3, which will be replaced by UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous.")
  result = self._query(query)
```

This doesn't happen with MySQL 5. I'm already using utf8mb4, so I shouldn't really see this.

Thanks!
