🩹 [Patch]: Encode all PowerShell files using UTF8 with BOM (#55)

## Description

This pull request makes a minor change to the `scripts/main.ps1` file.
It updates the file to include a Unicode Byte Order Mark (BOM) at the
beginning, which can help with encoding detection in some editors and
environments.
