flyway encoding problems with utf8 - flyway

Question

I am trying to use Flyway to migrate a MySQL database and everything works well except that I have encoding problems with cyrilic symbols that are replaced by '?' sign.
I am using the following Maven plugin.
<plugin>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>4.2.0</version>
<configuration>
<user>mysql</user>
<password>password</password>
<url>jdbc:mysql://192.168.1.6/schem2</url>
<encoding>UTF-8</encoding>
<schemas>
<schema>schem2</schema>
</schemas>
</configuration>
</plugin>
in datasource bean ...
jdbc:mysql://192.168.1.6/schem2?useUnicode=true&characterEncoding=UTF-8
It seems that everywhere the encoding is specified.

Answer 1

I had the same problem with Turkish characters, they were all converted to "?" char. As #saw303 said, I modified flyway.url from
jdbc:mysql://192.168.11.7:3306/test_db?autoreconnect=true
to
jdbc:mysql://192.168.11.7:3306/test_db?autoreconnect=true&useUnicode=true&characterEncoding=UTF-8
This modification solved the problem.
