encoding, looking for at forum

Hello Anton,
In encoding everything looks fine, still it continues to show warning.

<entry key='database.url'>jdbc:mysql://localhost:3306/traccar?useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>

What's the encoding for the address field?

characterEncoding=UTF-8

That's not column encoding. That's database connection encoding. I would recommend you to study MySQL documentation.
