SPSite: Issue with encoding when using custom ADFS claims provider

Details of the scenario you tried and the problem that is occurring Trying to create a site collection in which the Owner Alias is under a custom ADFS claims provider, the resulting MOF file changes the encoding and the characters that SharePoint understands. Making imposible to create a site collection under this scenario.

Verbose logs showing the problem VERBOSE: [Machinename]: [[SPSite]SiteName] Starting New-SPSite with the following parameters: Name=My Test Site; OwnerAlias=i:0ǵ.t|ADFS DEV|accountname; Template=STS#0; Url=https://testsite.com/sites/MyTestSite; Verbose=True … Exception of type ‘System.ArgumentException’ was thrown. Parameter name: encodedValue + CategoryInfo : InvalidData: (Microsoft.Share…SPCmdletNewSite:) [], CimException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletNewSite + PSComputerName : localhost Exception of type ‘System.ArgumentException’ was thrown. Parameter name: encodedValue + CategoryInfo : InvalidData: (Microsoft.Share…SPCmdletNewSite:) [], CimException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletNewSite + PSComputerName : localhost

Suggested solution to the issue Ensure the encoding is UTF-8 . Follow the explanation link to claims encoding in SharePoint here: https://social.technet.microsoft.com/wiki/contents/articles/13921.sharepoint-20102013-claims-encoding.aspx
