Move-Item, Remove-Item don't work with paths containing \, [, ] on unix #3414
Description
Steps to reproduce
On macOS or Linux touch '1\2'
Try mv 1\2 2, try rm 1\2
The real-world example of when you are getting \ without knowing it is PowerShell/Microsoft.PowerShell.Archive#11
The problem happens not only with Compress-Archive, but with other archive programs too. So macOS users need a way to bulk-rename files with \ in the name and PS doesn't provide a way to do it at the moment.
UPD: same problem for paths like [foo].
Expected behavior
PowerShell should be able to perform the operations
Actual behavior
Paths are getting normalized to 1/2
rm : Cannot find path '/Users/vors/dev/PowerShell/1/2' because it does not exist.
