What version of Codex is running?
codex-cli 0.2.0
Which model were you using?
qwen3
What platform is your computer?
Linux 6.6.87.2-microsoft-standard-WSL2 x86_64 x86_64
What steps can reproduce the bug?
At the input section, type any non-ASCII or Unicode character.
Examples: Such as, _but is not limited to_, Turkish characters (İ, ı, ş, ü, ğ, ö, ç), Chinese characters (e.g., 诶), or Russian Cyrillic characters (e.g., Й, Ц, У).
What is the expected behavior?
Codex should accept and correctly process typing containing non-ASCII (Unicode) characters without crashing. It should display these characters as entered.
What do you see instead?
The application crashes immediately upon by typing any non-ASCII or Unicode character.

I suspect https://github.com/openai/codex/pull/1467 may fix the issue: I'll try to get a release with the fix out soon, though there are some other changes I am also trying to get in.
Please try 0.3.0:
https://github.com/openai/codex/releases/tag/rust-v0.3.0
Also available via npm:
https://www.npmjs.com/package/@openai/codex
I'm still waiting for Homebrew to pick up the new version.
FYI, 0.3.0 is in Homebrew now: https://github.com/Homebrew/homebrew-core/pull/229365
Tried with, codex-cli 0.3.0. It's works as far i can test, no crashes yet.
