Bypass %20 conversion issue in rez cmd

I was facing to a weird issue, passing %20 characater to params %1 in cmd convert it to 0 instead of space.

Hopefully we can parse %20 character before cmd interpretation in powershell:

echo \"%1\" >> log.txt
Write-Output $args[0]
$replace=$args[0].replace('%20', ' ')
Write-Output $args[0]
iex "rez env <package> -- <script.py> '$($replace)'"
