[ESS] accent marks on windows

[Toby Hocking]

hi, I am installing ESS on a new work computer, which is in Quebec
(French speaking province of Canada).
I am having issues with display and entry of accent marks, for example
e with accent aigu é
For example when R starts up I see é instead of é

Do I need to tell emacs to use a particular character encoding for the
ESS buffer? How?
I expected this should "just work" (display the right character é)

More problematic, when I try to enter é in the *R* buffer, it
freezes/hangs the whole emacs window. C-g does not help/cancel, only
way to get out is to tell windows to kill emacs.

Any ideas?

Below is the environment from my eshell, if that helps.
Thanks in advance!
