Looks like a horrible hack to me. Recoding stuff to the client encoding
in the server outside the existing recoding mechanism looks pretty evil
to me. Plus, it does not address the problem of what happens to
messages sent before this, it just moves the point of "before" a bit
earlier for some special cases.
I think we have discussed more proper solutions earlier in this thread.
IMO the best approach would be for the client to include the client
encoding in the startup package.
