CLI shortcuts should work regardless of Korean/English input mode #4861
Description
What feature would you like to see?
When using Codex CLI, keyboard shortcuts (like Ctrl + C, Ctrl + L, etc.) don’t always work when the system input language is switched to Korean (Hangul).
Many other CLI tools and terminals handle shortcuts properly regardless of whether the input mode is English or Korean, but Codex CLI currently doesn’t.
It would be great if Codex CLI could recognize shortcut keys consistently across all language input modes, without requiring users to switch back to English first.
This would improve usability for developers in multilingual environments.

Additional information
OS: macOS (but same issue occurs on Windows and Linux)
Terminals tested: iTerm2, Terminal.app, and VS Code integrated terminal
When IME (input method editor) is set to Korean, most shortcuts stop responding.
This enhancement would make the CLI more accessible to international users who frequently switch between languages.
