I think it is better to avoid such a problem and fix system so server
would never send a message in the encoding, different from client one.
It is not a client job to convert encodings.
In most cases server does know which encoding client requests from the
very first protocol message. (if it is startup message).
So, server can easily tell if it is able to convert NLS messages into
the client desired encoding, and if not - fall back to untranslated
messages.
