What version of Codex CLI is running?

What subscription do you have?

Plus

Which model were you using?

any

What platform is your computer?

Linux 6.17.0-19-generic x86_64 x86_64

What terminal emulator and version are you using (if applicable)?

VSCode terminal

What issue are you seeing?

Typing a text with caps lock doesn't produce uppercase letters through VSCode terminal. I tested in the Linux terminal outside VSCode and it works. It also does not accept accented characters (example: ã, õ, á, é, â, ê, etc.).

What steps can reproduce the bug?

1. Open VSCode
2. Open the terminal (Shortcut: CTRL+J)
3. Start Codex CLI (Command: codex)
4. Turn Caps Lock on
5. Type any text

What is the expected behavior?

When caps lock is on, the letters should be in uppercase, and with caps lock off, lowercase. Accented characters should also be accepted.

Additional information

• I could reproduce this error only inside VSCode terminal.
• Pasting and copying a sentence with uppercase and accented letters works. Only typing these characters doesn't work.
