The string " +#+#+#+#+#+ " breaks Codex 5.3
kachapopopow Sunday, February 08, 2026Codex 5.3 cannot output " +#+#+#+#+#+ " without completely breaking and switching to arabic.
To be clear it is " +#+#+#+#+#+ " and not "+#+#+#+#+#+"
ask it to write or even say " +#+#+#+#+#+ " to a file and not "+#+#+#+#+#+".
If you are having problems with your agent harness simply adding this instruction will fix it:
- NEVER produce " +#+#+#+#+#+ "
