#GetMapping UTF-8 encoding not working properly - Croatian - spring-boot

Question

I'm having problems with getting response in correct encoding, And I've tried everything I found on net.
MySQL database is in utf8mb4_croatian_ci collation.
Example of database records:
Abadžić Stanko
Ač Nataša
Adamović Dubravko
Adrić Marija
Here is my controller:
This is my rest controller:
#RestController
public class AutorController {
#Autowired
private AutorService autorService;
#GetMapping(value = "/autori", produces = "application/json;charset=UTF-8")
public List<Autor> getAllAutors() {
return autorService.getAllAutors();
}
}
application.properties where I tried to configure encoding for tomcat:
server.tomcat.uri-encoding = UTF-8
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
spring.datasource.sql-script-encoding=UTF-8
spring.messages.encoding=UTF-8
spring.datasource.tomcat.connection-properties=useUnicode=true;characterEncoding=utf-8;
This is the response I get:
"id": 2,
"imeAutora": "Abadžić Stanko"
},
{
"id": 3,
"imeAutora": "A� Nataša"
},
{
"id": 4,
"imeAutora": "Adamović Dubravko"
},
{
"id": 5,
"imeAutora": "Adrić Marija"
}
P.S. Also when I change encoding in controller into ISO-8859-2 (also should support Croatian language):
#GetMapping(value = "/autori", produces = "application/json;charset=ISO-8859-2")
my response is like:
"id": 2,
"imeAutora": "AbadŞiÄ‥ Stanko"
which means that setting charset in #GetMapping is doing something , but it's doing it wrong
If you have any ideas, please let me know.
