unicode encoding error in windows

Comienza reproduciendo el fallo de la CLI empaquetada en un entorno MinGW o GitBash e inspecciona localstack/cli/localstack.py alrededor de print_version, donde el traceback llega a la salida de Rich. Compara ese comportamiento con PowerShell y verifica que la CLI se inicie correctamente sin el cp1252 UnicodeEncodeError.

when running the packaged CLI for windows, i get the following errors, which blocks the startup in the cockpit app https://github.com/localstack/localstack-desktop (where the same error is thrown when executing using spawn in a node process). i can reproduce it in a MinGW environment like GitBash

some observations:

• it works using powershell
• cp1252 refers to windows encoding: https://en.wikipedia.org/wiki/Windows-1252
• this is not related to the locale configuration
