As title says: i have VMWare Fusion 11.1.1, host is macOS 10.14.6, my path in host system to folders a want to share is /Volumes/süü/Share, guest is Windows 10 with last updates, i added Shared Folder and pointed one of it to path i mentioned above, in guest it is impossible to gain access to that folder, Windows just throws an error, something about permission, bla-bla-bla, typical error that i can't have access to this resource.
But! I added a few different Shared Folders without umlauts in path, like /Volumes/ExternalOne/Share, or /Volumes/macSSD/username/Share and everything works as expected, so i guess it is a bug.
