Subject: [PATCH] test: Clarify that Python UTF-8 mode is the default today for
 most systems

It will likely be the default for all systems, starting with Python
3.15, according to https://peps.python.org/pep-0686/#abstract.

It is hard to find a system other than Windows that has it not enabled
today. Nonetheless, Bitcoin Core requires UTF-8 in scripts and normally
enforces it via LC_ALL=C.UTF-8 or PYTHONUTF8=1.
