For me the logical behaviour is :
1) all text moving between client and server should be converted
2) text staying on server should stay in server encoding.
3) if someone has to move text produced by \copy on server, let hin do
it using a postgresql function defined as "read_text(path) returns text"
so the file gets converted using standard mechanisms.
4) for special cases we could add WITH CLIENTENCODING to copy
