Can't escape dollar sign in Powershell string

[johhnry]

I want to use a Powershell command that has dollar signs in string arguments (to render Houdini things) inside a Rez environment. The issue is that it works in Powershell by using single quotes but not when launching the command in a Rez resolved env.

Environment

• OS: Windows 10 Professionnel
• Rez version: 3.1.1
• Rez python version: Python 3.11.9

To Reproduce

1. Launch the following command in Powershell:

rez env python --shell=powershell -- Write-Output 'out.$F4.exr'

Expected behavior
It should print out.$F4.exr since single quotes escape the dollar sign in Powershell.

Actual behavior
It interprets $F4 as a variable and does the interpolation. (Note that it works when resolving the environment first and then launching the command)

How can I bypass this behavior?
