-a---- 5/13/2019 9:29 AM 0 [out].txt
PS> Set-Content -Path '.\`[out`].txt' -Value "value"

+ FullyQualifiedErrorId : ItemNotFound,Microsoft.PowerShell.Commands.SetContentCommand
PS> Add-Content -Path '.\`[out`].txt' -Value "value"

Expected behavior
Clear-Content and Get-Content work fine with the same path
PS> Get-Content -Path '.\`[out`].txt'
Content
PS:114> Clear-Content -Path '.\`[out`].txt'
PS:115> dir
Directory: F:\tmp\modules\temp
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 5/13/2019 9:32 AM 0 [out].txt
Set-Content and Add-Content should also work with that path.
Actual behavior
Add-Content and Set-Content don't work with the path.
