IBM DB2 values displayed as utf-8 text - database

Question

Once I connect to the database (DB2) to check the values in the tables, if they have special chars then I see their utf-8 text value:
I expected instead to see the correct: Tükörfúrógép.
I am still able to handle the value properly, but is there any configuration in the db that I am missing to display the value properly when checking the table?
More Info:
Connected to DB with Intellij and also tried with DbVisualizer.
The following JDBC connection was used in intellij:
jdbc:db2://(...)?characterEncoding=UTF-8;
Tried both with the characterEncoding and without getting the same results.
I am still able to handle the value properly, but is there any configuration in the db that I am missing to display the value properly when checking the table?
DB Version: v11 LUW
JDBC: com.ibm.db2.jcc -- db2jcc4 -- Version 10.5
Encoding being used: UTF-8
db2 "select char(value,10), char(name,10) from sysibmadm.dbcfg where
name like 'code%'"
1 2
---------- ---------- 1208 codepage UTF-8 codeset
2 record(s) selected.
UPDATE 1:
I was able to directly insert in the database values with special
chars, so starting to think this is not DB2 configuration missing but
maybe jdbc or other related issue.

You must have the following HEX string representation for given string Tükörfúrógép in UTF-8 database:
54C3BC6BC3B67266C3BA72C3B367C3A970.
But you have the following instead with repeating garbage symbols:
54C383C2BC6BC383C2B67266C383C2BA72C383C2B367C383C2A970
You may try to manually remove such a byte sequence with the following statement, but it's better to understand a root cause of such a garbage appearance in this column.
VALUES REPLACE (x'54C383C2BC6BC383C2B67266C383C2BA72C383C2B367C383C2A970', x'83C2', '');
SELECT REPLACE (TOWN, x'83C2', '') FROM ...;
