SSH Session through Citrix: Alt-Gr - Keys do not work

Hi all
I have RDP Manager installed on a Windows 10 Client.
I connect to the Client Desktop by using Citrix; then i start the RDP manager.
Then i use a stored SSH connection to connect to a Linux host.
I've disabled 'Application Keypad mode'.

My problem: Every character that can be typed in combination with Alt-GR does not work.


On my swiss-german keyboard i normally use Alt-Gr + 7 to type a pipe ( | ).


If i type Alt-Gr on the Windows 10 Client it works; but it does not within the SSH session.

Any ideas?

Best regards
Tom
