Hi,

I found a bug in Codex from ChatGPT.

When project files are located inside a directory whose name contains square brackets, for example:

[server]

Codex seems to have problems working with those files correctly.

What happens
file encoding gets broken/corrupted
saving changes may fail
in some cases Codex cannot properly write back modifications to the file

What steps can reproduce the bug?

Example

If the file is located in a path like:

[server]/somefile.ext

Codex may read it, but after editing it has trouble saving the changes correctly, or the file content ends up damaged because of encoding issues.

Expected behavior

Codex should handle folders with square brackets in their names normally and save edited files without changing encoding or corrupting content.

Actual behavior

Directories such as [server] appear to cause path handling or save/write issues, which leads to failed saves or broken file encoding.

Notes

This looks like the square brackets in the folder name may be incorrectly interpreted during file path handling.

Please investigate support for paths containing [ and ].

Thanks.

What is the expected behavior?
