+
+A client can set its character set encoding using the CHARCONV command:
+after receiving such a command, the server translates all message data
+received from the client using the set <client-charset> to the server
+encoding (UTF-8), and all message data which is to be sent to the client
+from the server encoding (UTF-8) to <client-charset>.
+
+The list of supported <client-charset>'s is implementation dependent.
+
+If a client sets its <client-charset> to the server encoding (UTF-8),
+it disables all conversions; the connection behaves as if no CHARCONV
+command has been sent at all in this session.
