Unable to rename VM names with non-ASCII characters (umlauts)

[Bernd Selig]

Unable to rename a VB with non-ASCII characters (umlauts) within VirtualBox or with VBoxManage.

With VBoxManage:

VBoxManage.exe: error: Could not find a registered machine named 'D:\VirtualBox Images\Win10 B³ro\Win10 B³ro.vbox'
VBoxManage.exe: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBoxWrap, interface IVirtualBox, callee IUnknown
VBoxManage.exe: error: Context: "FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())" at line 500 of file VBoxManageModifyVM.cpp 

The following error message occurs:

Die Einstellungen der virtuellen Maschine Win10 Buero konnten nicht nach D:\VirtualBox Images\Win10 Büro\Win10 Büro.vbox abgespeichert werden.
Could not rename the directory 'D:\VirtualBox Images\Win10 B�ro' to 'D:\VirtualBox Images\Win10 Buero' to save the settings file (VERR_ACCESS_DENIED).

Works here. Tested on Windows and Linux. I tried this both with VBoxManage (VBoxManage modifyvm OLD_VM_NAME --name NEW_VM_NAME) as well as with the GUI.

• Which version of VirtualBox are you using?
• Which Windows version (exact version number please)?

Actually VERR_ACCESS_DENIED looks much more like a permission problem. Are you sure that \dokumente und einstellungen\USER\VirtualBox VMs\* is writable for the current user?

After your answer I did some more tests.

1. I try it again with VBoxManage on the windows console with my batch script and it still didn´t work, because the encoding of the batch file to the console went wrong. On the console the umlaut >ü< was translated to a special character and therefore the VM wasn´t found. That´s no error of the VirtualBox.
2. Another problem was the way I used the command line tool: My call contained in the parameter --name "VM-name" the complete path of the VM with the destination name, e.g. --name "C:\Users\MyUser\VirtualBox VMs\Windows Büro\..." like the VM source parameter. After I removed the path of the last parameter and type the command directly into a windows console it also worked.
3. And I try it again with the GUI on the same computer with the same user and then it worked as expected. I don´t know why.

Sorry for the ticket and the circumstances. I hope my ticket will help another user during trouble shooting ;-).

Thanks for the information.
