2.18.2 CodePage Property

The CodePage property MUST have the property identifier 0x00000001, MUST NOT have a property name, and MUST have type VT_I2 (0x0002). Every property set MUST have a CodePage property and its value MUST be a valid code page identifier as specified in [MS-UCODEREF] section 2.2.1. Its value is selected in an implementation-specific manner.<2>

The CodePage property of a property set affects the representation of the CodePageString and DictionaryEntry packets. The value CP_WINUNICODE (0x04B0) indicates that the strings in these packets are encoded as arrays of 16-bit Unicode characters. Any other value indicates that the strings in these packets are encoded as arrays of 8-bit characters from the code page identified.
