Failed to output chinese emoji to mysql

My mysql uses code utf8mb4, and mysq's temporary table code is utf8mb4,
When I insert data into mysql temporary table, it has the following error:
`org.embulk.exec.PartialExecutionException: java.lang.RuntimeException: java.sql.BatchUpdateException: Incorrect string value: '\xF0\x9F\xA4\xA3' for column ......`

Can someone help me solve this problem? thanks.

Start by reproducing the reported insert of a Chinese emoji into a MySQL utf8mb4 temporary table through the JDBC output plugin, then trace the connection and temporary-table encoding settings involved. Done means the same data inserts without the reported BatchUpdateException, with a regression test covering the emoji case.
