3.1.4.3.6 String Sorting

Every server MUST support sorting on Unicode string representations for the PidTagDisplayName property. If the server supports the SortTypePhoneticDisplayName sort order, it MUST also support sorting on Unicode string representation for the PidTagAddressBookPhoneticDisplayName property. The server MUST minimally support the LCID NSPI_DEFAULT_LOCALE flag. This sorting conforms to that specified in [MS-UCODEREF].
