As I have written [1], defining

    PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '

in /etc/profile or .bashrc works fine in RXVT, MRXVT, URXVT, XTERM,
(KDE)Konsole WITHOUT Emacs.

i.e. the code '\[\e]0;\w\a\]' prints the working directory as title of
RXVT, MRXVT... window; the remains gives the terminal prompt in the form

    blank line (\n)
    user AT host (in green) working directory (yellow)
    $ (white)

As reported here [2], the main problem Emacs meets is with the window
title '\[\e]0;\w\a\]' (and perhaps this is to be expected)

In any case, have you some comment on how to solve the other question I
pointed out in [2], i.e. setting in .emacs

    (setenv "PS1" "prompt>")

works, but

    (setenv "PS1" "address@hidden \w\n$ ")

doesn't: Emacs starts with errors:

    "An error has occurred while loading '[...]/.emacs':
     error: Non-hex digit used for Unicode escape"


Cheers,
Angelo.
