How to setup Utf-8 for MySql on Ubuntu?

I have the next table:

mysql> SHOW VARIABLES LIKE 'char%';+--------------------------+----------------------------+| Variable_name            | Value                      |+--------------------------+----------------------------+| character_set_client     | utf8                       || character_set_connection | utf8                       || character_set_database   | latin1                     || character_set_filesystem | binary                     || character_set_results    | utf8                       || character_set_server     | latin1                     || character_set_system     | utf8                       || character_sets_dir       | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+8 rows in set (0.01 sec)

I use the JDBC driver. Tables with text fields that must support utf8, is created like this:

jdbcTemplate.execute("CREATE TABLE IF NOT EXISTS users"+"(id BIGINT NOT NULL AUTO_INCREMENT,"+"name VARCHAR(45),"+"................."+"ENGINE=InnoDB DEFAULT CHARSET=utf8mb4");

On the local machine, everything works. But on the Ubuntu server, I'm getting "?????" instead normal name in the UTF-8. How to fix it? The application works via Nginx. Perhaps this is the problem?
