The Apple File Services component of Mac OS X Server 10.0.3 implements Apple Filing Protocol (AFP) version 3.0, which can use Unicode filenames. Unicode offers multiple language support within one character set.
To allow for backward compatibility with older AFP versions (which do not support Unicode filenames), the Server Admin application allows you to specify the character set (or "encoding") earlier clients are to use when connecting to the server. The default encoding specified for earlier AFP clients is the Roman character set. For example: If you have Mac OS 8.6 clients using Japanese characters to connect, you should set Apple File Service to use Japanese encoding for earlier clients.
Follow these steps to change the encoding:
1. Open Server Admin and log in.
2. Click the File & Print tab.
3. Click the Apple icon and select Configure Apple File Service from the submenu.
4. Click the Access tab.
5. Choose the correct character set for your clients from the Encoding for older clients pop-up menu.
