Attempts to mount NFS datastores with names in international languages result in failures.
The use of non-ASCII characters for directory and filenames on NFS storage might cause unpredictable behavior. For example, you might fail to mount an NFS datastore or not be able to power on a virtual machine.
ESXi supports the use of non-ASCII characters for directory and filenames on NFS storage, so you can create datastores and virtual machines using names in international languages. However, when the underlying NFS server does not offer internationalization support, unpredictable failures might occur.
Always make sure that the underlying NFS server offers internationalization support. If the server does not, use only ASCII characters.
