Send text or a command to Battle.net using this packet.
For STAR/SEXP/SSHR/JSTR, Text is UTF-8 encoded (WIDESTRING).
It is generally accepted as unwise to send any character below a space (0x20): this includes line feeds, carriage returns & control characters. The maximum number of characters is 224 per message including the null-terminator (so really only 223 characters), any longer and it becomes trimmed by Battle.net.
If you send a line feed and/or a carriage return, Battle.net disconnects you and IP bans you for 5 minutes.
