The Mac OS X client is Unicode enabled. New clients storing data on the server for the first time require no special set up.
The server automatically stores files and directories as Unicode enabled. However, if you are upgrading to the Unicode-enabled client, you need to plan the migration of existing file spaces so they can support Unicode.
Any file spaces that are already on the server must be renamed so Unicode-enabled file spaces can be created. Use the autofsrename option rename existing file spaces.
