As Chong said you must use a non--english/us locale.
I have the same problem here, my prompt is not "Password" but "Mot de
Passe", due to my french locale.
All the prompts for password (e.g su/sudo) in the emacs shell use a
cryptic regex.
Setting it is a pain, i always have undesired side effects trying to set
them. (shell and eshell).

For shell (don't work in eshell):
A workaround for "su" is creating an alias in bashrc:

alias su="LC_ALL=C su -l"

For sudo:
alias sudo="sudo -p Password: "

For eshell i didn't find good solution appart putting in my .emacs:

(setenv "LC_ALL" "C")

Work fine but may create other encoding problems in others places.

The best thing should be that all emacs shell don't obey to locale
setting for password prompt, i thing the word "password" in
international well known.
