codex - 💡(How to fix) Fix Codex app: Korean `/압축` slash command posts only `축` when submitted with Enter [1 comments, 2 participants]

Summary

Korean localized slash command /압축 works functionally, but when submitted with Enter, only the final character 축 is posted into the chat history.

This does not happen when selecting the command with the mouse, and English slash commands do not seem to have the same issue.

What happened

When I type /압축 in the Codex desktop app and press Enter:

• The compaction itself appears to run correctly.
• However, the submitted chat message becomes only 축.

So the bug is not that compaction fails. The bug is that the Korean slash command is rendered/submitted incorrectly after pressing Enter.

Expected behavior

Submitting /압축 with Enter should behave the same as selecting it with the mouse:

• run the compaction command
• not post only the final character 축 into chat history

Actual behavior

Pressing Enter after typing /압축 posts 축 into the chat.

Reproduction steps

1. Open Codex desktop app.
2. Type /압축 in the composer.
3. Press Enter.
4. Observe that 축 is posted into the chat history.

Comparison

• /압축 + Enter: compaction runs, but 축 is posted into chat.
• /압축 selected by mouse: works normally.
• English slash commands such as /compact: work normally.
• Other localized languages: not tested.

Environment

• App: Codex desktop app
• OS: macOS
• Input/language: Korean
