Code Review by Qodo

🐞 Bugs (1) 📘 Rule violations (0) 📎 Requirement gaps (0)

1. Encoding cookie displaced 🐞 Bug ⚙ Maintainability

Description

In setup.py, the "# -*- coding: utf-8 -*-" declaration was moved down to line 14 by the inserted
license block, so Python will not treat it as an encoding declaration. This makes the encoding
cookie ineffective and can cause future breakage if non-ASCII content is added while relying on that
declaration.

Code

setup.py[R14-16]
# -*- coding: utf-8 -*-
import sys

Evidence

The PR inserts the license header at the top of setup.py, pushing the encoding cookie to line 14.
Per PEP 263, an encoding declaration is only recognized if it appears on the first or second line of
the file (after an optional shebang), so this declaration will be ignored.

setup.py[1-18]
Best Practice: PEP 263

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`setup.py` contains an encoding declaration (`# -*- coding: utf-8 -*-`) that was pushed down by the new license header block. Python only recognizes encoding cookies when they appear on line 1 or 2 (after an optional shebang), so the current declaration is ineffective.

## Issue Context
This is a low-risk but real correctness/maintainability issue: the encoding cookie currently provides no value and could mislead future edits.

## Fix Focus Areas
- setup.py[1-16]

## Suggested fix
Either:
1) Remove the encoding cookie entirely (Python 3 defaults to UTF-8), or
2) Move the encoding cookie to line 1 (or line 2 if there is a shebang), and keep the license header immediately after it.
