Yes it is the same

I found what is not working.

I use an alias in my .bashrc to force emacs shell using the word Password
as prompt for su command:

,----
| alias su="LC_ALL=C su -l"
`----

Emacs shell support that but term doesn't.
Without that alias or when running sh instead of bash term work as expected.

1) Running term with the alias:

,----
| thierry@tux ~ $ echo $UID
| 1000
| thierry@tux ~ $ su
| Password: 
| thierry@tux ~ $ echo $UID
| 1000
`----

2) Running term without alias:

,----
| thierry@tux ~ $ echo $UID
| 1000
| thierry@tux ~ $ su
| Mot de passe : 
| tux thierry # echo $UID
| 0
`----

3) Running Emacs shell with the alias (M-x shell):

,----
| thierry@tux ~ $ echo $UID
| 1000
| thierry@tux ~ $ su
| Password: 
| tux ~ # echo $UID
| 0
`----
