ASCII
When set on a player, it forces the client character set in all sessions to be 7-bit ASCII. All ISO 8859-1 and UTF-8 characters are then translated and approximated with 7-bit ASCII characters. Any character which cannot be approximated are shown with a single '?'.
The default is for each client to negotiate its character set ability on a per session basis.
