Mmmmkay, answering to myself (you never know, maybe it will be useful to
someone else later ...): the answer to that is in the general
interprocess comunication in Emacs. I ended up doing this:

--8<---------------cut here---------------start------------->8---
(setq default-process-coding-system '(utf-8-unix . utf-8-unix))
--8<---------------cut here---------------end--------------->8---

and everything works fine now.

Having to set this by hand is a bit counter-intuitive though - would it
make sense to have babel set =coding-system-for-read= and
=coding-system-for-write= when running a subprocess ? From what I
understand, =shell-command-on-region= does that automatically but
=org-babel-eval= uses a temporary buffer which loses the encoding choice
for the .org file buffer.

Sorry for the noise, and thanks to all for this excellent tool ! I am
getting addicted to org and babel by the minute ...

Cheers,
