Cannot force UTF-8

[Grimshad]

What version of Codex is running?

vscode extension 0.4.12

Which model were you using?

codex high, medium, and low

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What steps can reproduce the bug?

Codex overwrites emoji's with unicode jibberish. This is what gpt 5 said about it:

Codex extension bug → It’s writing the file contents with the wrong encoding (double-encoding UTF-8 into CP1252/Latin-1), which produces mojibake like ðŸ....

Config.toml can’t fix it → There’s no supported config option today to change file encoding. Codex assumes UTF-8, but sometimes on Windows it falls back incorrectly when saving.

What is the expected behavior?

Don't automatically replace emoji with unicode when editing files

Oh, I forgot to mention it also does stuff like this all the time which causes problems instead of adding proper new lines, it add literal new lines:

if (pointIndex !== null) {\r\n hook.selectedIndex = pointIndex;\r\n hook._isDraggingPoint = true; // Start dragging the selected point\r\n // Clear other selections when selecting a point\r\n hook.selectedLine = null;\r\n hook.selectedShape = null;\r\n hook._hoverLightHandle = null;\r\n if (typeof hook._updateCursor === "function") {\r\n hook._updateCursor();\r\n }\r\n hook._renderPoints();

Same here, it broke my whole project adding those ðà on every file

I often encounter this issue as well. Observation shows that it seems to be implemented by writing Python scripts to edit files, sometimes altering the UTF-8 file header to BOM.

It's incredibly frustrating. Windows, Codex.

This should be fixed in the latest versions of codex.
