Expecting utf8mb4 charset on new table

Hi,

I'm creating a new simple table where I don't specify a charset. I expect it to have utf8mb4, but it says utf8.

The server vars all point to utf8mb4

mysql> show global variables like '%char%';
+--------------------------+--------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------+
| character_set_client | utf8mb4 |
| character_set_connection | utf8mb4 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | utf8mb4 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+


I create the new table from a text file via command line
(mysql ... < table_file.txt):

CREATE TABLE `zzzTest` (
`Count` int(10) unsigned NOT NULL DEFAULT '0',
PRIMARY KEY (`Count`)
)

Then mysqldump it, it says that the default charset is utf8, not utf8mb4. Why?

DROP TABLE IF EXISTS `zzzTest`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
SET character_set_client = utf8mb4 ;
CREATE TABLE `zzzTest` (
`Count` int(10) unsigned NOT NULL DEFAULT '0',
PRIMARY KEY (`Count`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
