The sentence quoted from the docs is perhaps less than a model of 
clarity. I would take it to mean that no client-encoding -> 
server-encoding translation will take place. Does it really mean that 
the server will happily accept any escaped byte sequence, whether or not 
it is valid for the server encoding? If so that seems ... odd.
