Win32_TSLicenseReport not generating report when AD has Japanese usernames

Question

$fileName = (Invoke-WmiMethod Win32_TSLicenseReport -Name GenerateReportEx).FileName
$fileEntries = (Get-WmiObject Win32_TSLicenseReport | Where-Object FileName -eq $fileName).FetchReportEntries(0, 0).ReportEntries

These commands succeed when I have ONLY usernames in english alphabets. The moment I add a username in Japanese language, the $fileEntries comes out as empty. When I manually generate report and save it, I cannot see the entry of usernames saved in Japanese language. This definitely seems like an encoding issue. How to get past this?

Answer 1

That looks like it might be a problem with WMI, not PowerShell. Have you tried using Invoke-CIMMethod (using the same class name)? It may not make any difference, but it's easy enough to try. The WMI and CIM may use different MOF files to acquire the and process the information.

Or it may be a problem with the installed languages on the RDS server (where the report is created). But that's a Windows configuration issue, not a PowerShell problem.
