Could you please specify how to do this? I just installed mlterm in my
Kubuntu and run gnuclient -nw but then nothing happened, not even a
familiar gnuclient window poped up (I have gnuserver running). How am I
suppose to write a RL2 language like Hebrew?

I tried this out once, it is very unstable and memory hungry.

Ok fair enough. The critical function is 
poor-mans-bidi-decode-buffer
I e-debugged that function to see why the cursor in the BIDI buffer is
not moving and the following line seems to be the problem:
245:
    (goto-line line-number)

In GNU emacs this jumps to the correct line while Xemacs does not do
anything. On explanation could be the line at beginning of the function

221
  (let ((line-number (line-number-at-pos))

In GNU emacs (line-number-at-pos) returns beside the line number also
sort of UNICODE chars, while Xemacs does not. That might explain it, but
I have no idea. If this has a quick fix, I would be greatful, if not,
well then either I might use your mlterm solution or use GNU emacs for
bidi stuff.
