What's Wrong?

I cannot enter @ in the Claude CLI when in PHPStorm.
It works fine in e.g. VS Code. Asking Claude about it I get this:

This might be a bug - the Claude Code CLI should properly handle Danish keyboard input. Since this is blocking basic functionality, I'd recommend reporting it:

You can report this issue at: https://github.com/anthropics/claude-code/issues

When reporting, mention:

• macOS version (you're on Darwin 25.0.0)
• Danish keyboard layout
• Apple Magic Keyboard
• Option + å produces wrong character instead of @
• Expected: @ symbol for file references

I don't recognize the reference to option + å. @ on a danish keyboard is found by holding down Option and pressing the button to the right of Ø (displaying an apostrophe, an asterisk and an @)

This key combination gives me this: þ

What Should Happen?

Pressing the normal key combination for an @ on a danish keyboard should give me an @ on the command line not a þ
