What issue are you seeing?

In the Codex App, when the UI is running in Chinese, the "Implement this plan?" confirmation dialog renders numbered options with a Chinese full stop after the number, for example 1。 and 2。, instead of the expected 1. and 2..

This looks like a localization/punctuation bug in the app UI rather than intentional localization. These are ordered-option markers / keyboard shortcuts, so replacing . with 。 makes the numbering look off and inconsistent.

What steps can reproduce the bug?

1. Use the Codex App in a Chinese UI environment.
2. Trigger a plan confirmation dialog such as "Implement this plan?".
3. Look at the option numbering.
4. The options are rendered like 1。 Yes, implement this plan and 2。 No, ....

What is the expected behavior?

The option markers should remain ASCII ordered-list markers: 1. and 2..

The language of the option text can be localized, but the numbering punctuation for these UI choices should not change to 。.

Additional information

• This appears to be specific to the Codex App UI.
• Public codex TUI code paths use ASCII 1. numbering for similar selection UIs, so this may be happening in an app-specific localization/rendering layer.
