Summary

???are the UTF-8 BOM bytes rendered as replacement characters. Wheniwrdownloads the script and pipes it as a string toInvoke-Expression, PowerShell does not strip the BOM — it treats it as part of the command name, causing an immediate crash.Fix
Re-encoded all three
.ps1files as UTF-8 without BOM usingSystem.Text.UTF8Encoding($false). The scripts are otherwise identical — only the invisible leading bytes changed.Testing
