Bug Report: spanish characters can't be typed - possibly non-ascii

What version of Codex is running?

0.27.0

Which model were you using?

gpt-5 (irrelevant here)

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

Here are some of the chars that fail: "ñ", "í", "", which are non-ascii.

Open codex cli on windows, type or paste them, they won't be displayed nor will be able to be read by codex.

for example, if you paste this string: á, é, í, ó, ú, ü cli will see this: , , , , , ,

What is the expected behavior?

Should be able to write these characters.

Linux:

What do you see instead?

Well, can't type those.

Additional information

• Happens on windows but not Linux.
• I can do codex "ñ" (non-tui) as a command and it works fine.
• CLI appears to be able to render said chars properly when asked to.
• This bug only happens when you attempt to type or paste said chars.
