What's Wrong?

Claude code does not write @ sign on nordic keyboards. This is since it uses option as meta key, whereas nordic keyboards require you to press option+2 for writing characters such as @. Claude also does not use zsh keybindings that overrides the behavior: https://gist.github.com/villesau/ebe834fd943f8ef0eb39ef96dcfa5788

What Should Happen?

option+2 (writing @ sign) should write @ character.

Error Messages/Logs

None

Steps to Reproduce

Use nordic keyboard (finnish, swedish) and try to write @ using option+2. Using nordic keyboard layout might be enough to reproduce. Might require to toggle "Use Option as Meta key" toggled on in the settings. If it is not toggled in the settings, writing @ character works but option + enter does not insert new line so it is similarly handicapped.
