Well, you can *try* using other encodings, but there are enough known
problems that I don't think it will work pleasantly unless client and
server encodings are the same all the time.

Okay, make that "sent just after the change is made". So it looks like
you should receive a string in the new encoding. I can't offhand think
of a way to test this though --- are any of the reported settings
interesting from an encoding standpoint?

Hm. This is true for all the "backend-safe" encodings but I believe
not for all the supported client encodings. Tatsuo might have more of
a clue than me about likely failure cases.
