# UTFANSWF v23 Windows Console Portability Hotfix — 2026-08-19

Scope: console-output portability only.

The canonical Row 20 gate previously printed the Unicode label `χ²/dof` after writing its result JSON. On Windows consoles using a legacy code page such as CP-1252, encoding the Greek chi character could raise `UnicodeEncodeError` after the numerical gate had completed.

Hotfix:
- `ROW 20 — ...` -> `ROW 20 - ...`
- `χ²/dof: ...` -> `chi2/dof: ...`

No numerical calculation, dataset, threshold, gate criterion, result JSON schema, promoted prediction, `main.tex`, or `main.pdf` is changed. The top-level harness already treats child-process failures as blocking and exits nonzero; this hotfix removes the console-encoding failure itself.
