cmd.exe: aws ssm start-session: Cannot enter "$" or "@" w/Norwegian keyboard layout, nor paste

[andersnm]

Describe the bug

I have a Norwegian keyboard, and when I press AltGr+4 for $, or AltGr+2 for @ in a CLI SSM session then nothing happens. $ and @ works everywhere else.

Likewise, if I paste anything containing $ or @ then the special characters are ignored.

If I change keyboard layout to US, then I can press Shift+4 and Shift+2 for $ and @ respectively. But I still cannot paste.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

If I type or paste a string with "$", I expect "$" to be included in the CLI SSM session.

Current Behavior

If I type or paste a string with "$", nothing happens in the CLI SSM session.

Reproduction Steps

• Have Windows 11 with Norwegian keyboard layout
• Have EC2 instance with recent Amazon Linux (mine has Linux/6.1.127-135.201.amzn2023.x86_64)
• Connect to the EC2 instance using aws ssm start-session ...
• Type $ or @, or paste a string containing either or both
