nType (2 bytes): A 16-bit integer that identifies the type of chat message being transmitted. This field MUST be set to GAME_MSGID_CHAT (1).
strChatString (400 bytes): A Unicode-format chat message string. The application SHOULD send 200 Unicode characters. If the length of the actual chat string is less than 200 Unicode characters, then the value specified in strChatString SHOULD be padded. If the length of the chat string in the received packet is less than 200 Unicode characters, the receiver SHOULD send an acknowledgment for the message, and the receiver SHOULD discard the message.
