3.1.1.2.3 Conversion Rules for String Values Specified by the Server to the Client

When returning string values as output parameters for methods where the method allows for both Unicode and 8-bit character representations, the server MUST follow these conversion rules.

If the native type of a property is PtypString and the client has requested that property with the type PtypString8, the server MUST convert the Unicode representation to an 8-bit character representation in the codepage specified by the CodePage field of the pStat parameter prior to returning the value.

If the native type of a property is PtypString and the client has requested that property with the type PtypString, the server MUST return the Unicode representation unmodified.

If the native type of a property is PtypString8 and the client has requested that property with the type PtypString, the server MUST convert the 8-bit character representation to a Unicode representation prior to returning the value. The 8-bit character representation is considered to be in the codepage CP_TELETEX.

If the native type of a property is PtypString8 and the client has requested that property with the type PtypString8, the server MUST return the 8-bit character representation unmodified.

Servers MAY<8> undertake other conversions and substitutions for specific properties.

The following table specifies NSPI methods, that are capable of returning string values in both Unicode and 8-bit character representations, and the methods for which the conversion rules are applicable.
