Consider that you want to enable "UTF-8", for example, then:
- On the Application Server page, click on the name of the server that you want it to be UTF-8 enabled.
- On the settings page for the selected application server, click Process Definition.
- On the Process Definition page, click Java Virtual Machine.
- On the Java Virtual Machine page, specify -Dclient.encoding.override=UTF-8 for Generic JVM Arguments and click OK.
- Click Save on the console taskbar.
- Restart the application server.
This can work for any Character Encoding.
