The check-windows-footguns.py script outputs a checkmark (U+2713) and
cross (U+2717) to report results. Windows terminals default to cp1252,
which cannot encode these characters, so running the script on Windows
threw a UnicodeEncodeError before any results were printed.
This made the tool completely unusable on the exact platform it exists
to help -- a developer on Windows trying to check their code for
Windows-safety issues would just get a crash instead.
Fix: reconfigure stdout and stderr to UTF-8 at the start of main(),
before any output is produced. Verified on Windows 11 Home with
Python 3.13 (terminal defaulting to cp1252).
