I can add to the information that swedish characters å, ä and ö does not work either. Total crash as soon as I write any of them to the prompt.
Pasting other things too!
Try pasting this prompt:
Dans les fichiers *.py, il y a des instructions dans les commentaires commençant par ‘CODEX’. Exécute ces instructions pour modifier le code. Enleve le commentaire ensuite. Utilise toujours des espaces et non ‘ ' « narrow no‑break space » (U+202F). N’enleve aucun commentaire existant sauf s’il n’est plus valable.
This may be the same as https://github.com/openai/codex/issues/1450 since my prompt contains special char narrow no‑break space .
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
It works, thank you!
