Description:
The data export for tables (transactional data included) fails with the following error message:
12:05:46 Dumping DLDB (TblÜbungsstunden)
Running: mysqldump.exe --defaults-file="c:\temp\tmpi0nw5qn3.cnf"  --host=mysql-3d79e92b-taunusstein-1ea6.h.aivencloud.com --port=12839 --default-character-set=utf8 --user=avnadmin --protocol=tcp "DLDB" "TblÜbungsstunden"
Error executing task: 'utf-8' codec can't decode byte 0xdc in position 728: invalid continuation byte
Operation failed with exitcode None
Error executing task cannot access local variable 'result' where it is not associated with a value
12:05:46 Export of C:\Users\IEuser\Documents\dumps\Dump20260521 (5) has finished

I could isolate that the failing table data export is related to the fact that the table name contains at least one Umlaut (TblÜbungsstunden).

The MySQL Db is hosted as a managed service in the AIVEN cloud. A command-line access is not given at this time. 

Is there any option available in the MySQL Workbench to met 'utf-8' problem?

How to repeat:
Steps to reproduce 
1. Open MySQL Workbench
2. Go to "Server" > "Data Export"
3. Chose your Schema to be exported.
4. Chose your Tables (with Umlaut) to be exported.
4. Klick on "Start Export".
