Thanks to a post by Lon in the


thread on the internettablettalk forums I could solve my troubles
using the Nokia SU-8W BT keyboard in remote emacs sessions.

If I understand a related thread on the developers list correctly, the 
xim input method, which is activated by a BT keyboard, tries to convert/pack
characters into UTF-8, with mixed success. The key for my problem, however,
is to make emacs aware that all 8bits of the characters sent are
relevant. Interestingly, just doing something like

(let ((value (current-input-mode)))
  ;; The third arg only matters in that it is not t or nil.
  (set-input-mode (nth 0 value) (nth 1 value) 'iso-latin-1 (nth 3 value)))
                                 this should make emacs interpret 8bit
                                 characters correctly

is *not* enough, but forcing emacs into full utf-8 mode does the trick:
My .emacs on my work machines now contains:

(if (getenv "_NOKIA770")
    (progn (setq locale-coding-system 'utf-8)
           (set-terminal-coding-system 'utf-8)
           (set-keyboard-coding-system 'utf-8)
           (set-selection-coding-system 'utf-8)
           (prefer-coding-system 'utf-8)))

Hope that helps someone else! I still need to add some define-keys,
since the software keyboard for some strange reasons doesn't send <RET>
but <kb-return> (???), but otherwise I am now quite happy ...
