Hi,
I'm struggling with automating ndmpcopy in a Powershell script.
It works, but only with English (ASCII) characters.
Example code:
#prepare
import-module dataontap
$cred= (Get-Credential) # provided root password
$controller = Connect-NaController ucnlabfiler07 -Credential $cred
$srcdir = "/vol/volroot/home/gut"
$dstdir = "/vol/volroot/home/restore"
#both directories already exist on same controller, just for testing
#start ndmpcopy
$copy = Start-NaNdmpCopy -SrcController $controller.Address -SrcPath $srcdir -DstController $controller.Address -DstPath $dstdir -SrcCredential $cred -DstCredential $cred -SrcAuthType Md5 -DstAuthType Md5
# After some time, fetch the result
Get-NaNdmpCopy
Id State SrcPath DstPath BackupBytesProcessed BackupBytesRemain
-- ----- ------- ------- -------------------- -----------------
1 SUCCESS /vol/volroot/home/gut /vol/volroot/home/restore/ 23 KB 0
So, it's generally working fine.
Same also works by invoking ndmpcopy through SSH
Invoke-NaSsh -Command "ndmpcopy $($srcdir) $($dstdir)"

However, as soon as one of my source or destination path components contains non-English characters, both approaches break:
$srcdir = "/vol/volroot/home/blöd"
$dstdir = "/vol/volroot/home/restore"
$copy = Start-NaNdmpCopy -SrcController $controller.Address -SrcPath $srcdir -DstController $controller.Address -DstPath $dstdir -SrcCredential $cred -DstCredential $cred -SrcAuthType Md5 -DstAuthType Md5
#wait a moment
$result = Get-NaNdmpCopy
$result

Same happens with SSH invocation:

Other cmdlets like Read-NaDirectory or New-NaDirectory accept (and return) the umlaut:
Read-NaDirectory /vol/volroot/home/blöd

I just can't get ndmpcopy to work with umlauts ![Smiley Mad Smiley Mad](/i/smilies/16x16_smiley-mad.png)
My (root) volume language on the filer is de.UTF-8. My Powershell host is a German Windows 8.1.
I can successfully run the ndmpcopy command (including umlauts in path names) from a PuTTY session to the same controller. But cannot using PoSh.
I alread played with
$OutputEncoding =[System.Text.Encoding]::UTF8
$OutputEncoding =[System.Text.Encoding]::Default
but the Invoke-Na* cmdlets seem to ignore it.
It's driving me crazy - I'm out of ideas.
Can anyone point me to the right direction?
