Powershell, what's wrong with the encoding in a variable?

Question

PowerShell

Good afternoon!
Necessary: ​​on Windows, automate the sending of files by mail from a certain folder in separate letters, so that one letter is one file.
Of the nuances: The path to the folder contains Russian letters and square brackets.
A simple script was written on PS:

$filename = "sendmail.log"
$scriptPath = split-path -parent $MyInvocation.MyCommand.Definition #Директория где запущен скрипт, без последнего "\"
$path = $scriptPath + "\" + $filename

function logging ($LogMessage){
  "$(Get-Date -UFormat "%d-%m-%Y %T") $LogMessage"|out-file $path -Append
}

function SendMailToUser($To,$ErrorTo) {
    $From="[email protected]"
    $Subject="Invoice"
    $Body="Invoice"
    $Password="12345"
    $SecPassword=New-Object -TypeName System.Security.SecureString
    $Password.ToCharArray() | foreach {$SecPassword.AppendChar($_)}
    $Credintial=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $From,$SecPassword
  $smtpServer="test.ru"
  $encoding = [System.Text.Encoding]::UTF8
  $InvoicesPath = 'B:\TEMP\рус[1]\*'
    $invoices = Get-ChildItem $InvoicesPath | % { $_.FullName }
    foreach ($invoice in $invoices)
    {try{
      Send-MailMessage -From $From -To $To -Subject $Subject -Body $Body -Credential $Credintial -SmtpServer $smtpServer -Attachments $invoice -Encoding $encoding -ErrorAction Stop
      logging -LogMessage "$Invoice sent successfully"
      Remove-Item $invoice
      logging -LogMessage "$Invoice cleared successfully"
      }
    catch{
      $ErrorSubject="Error sending: $invoice"
      $ErrorBody="$(Get-date)111 Error:$($Error[0])"
      Send-MailMessage -From $From -To $ErrorTo -Subject $ErrorSubject -Body $ErrorBody -Credential $Credintial -SmtpServer $smtpServer -Encoding $encoding
      logging -LogMessage "$Invoice was not send! Error:$($Error[0])"
      }
    }
}

SendMailToUser -To "[email protected]" -ErrorTo "[email protected]"

When executed, it gives an error:

Get-ChildItem : Не удается найти путь "B:\TEMP\С?С?С?", так как он не существует.
C:\bin\sendmail.ps1:28 знак:17
+     $invoices = Get-ChildItem $InvoicesPath | % { $_.FullName }
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (B:\TEMP\С?С?С?:String) [Get-ChildItem], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand

Tried to use get-childitem parameter -LiteralPath, didn't help, different escaping characters and so on. I ask for your help, I do not know where to dig further. Works with the path in Latin letters.

Answer 1

Most likely you have a script file in utf-8 or utf-16 encoding without BOM. Try resaving it in utf-8 encoding with BOM or in 1251

Answer 2

try instead:
put:
and if it doesn't help, then add -LiteralPath like this:

$invoices = Get-ChildItem -LiteralPath $InvoicesPath | % { $_.FullName }
