You can't: buffers are always encoded in Emacs-mule (or its own
version of utf-8 in Emacs 23), or in unibyte (in which case the
position-byte function becomes rather pointless).  I don't know what
you call "set buffer-encoding appropriately".

You can. presumably, talk in unibyte with your server and do the
encoding and decoding on the way to the buffer manually.  In which
case you can just use buffer positions in characters as synonyms with
those in bytes.
