What issue are you seeing?

I can't find any file using @ in the Codex CLI.

What steps can reproduce the bug?

1. Open the CLI.
2. Type @ to search for a file.
3. Try to type a filename containing non-English characters (e.g., Chinese, Japanese).
4. Observe that the search does not return the expected files.

What is the expected behavior?

The search should correctly identify and suggest files with non-English characters when using the @ symbol.
