You are right I can't easily upgrad to Emacs 23.1, but if necessary I'll
try to make a case with our IT people.

I did customize Emacs 22.3 to prefer ISO-latin-1 a little while ago because
I had problems with LaTeX files (I also heavily use LaTeX through Emacs'
AucTeX) with europeans accents; if I go to UTF-8 will the problems with
LaTeX come back?

Here are the defaults locale settings:
Sys.getlocale("LC_ALL")
[1] "LC_CTYPE=en_US.UTF-8;
LC_NUMERIC=C;
LC_TIME=en_US.UTF-8;
LC_COLLATE=en_US.UTF-8;
LC_MONETARY=C;
LC_MESSAGES=en_US.UTF-8;
LC_PAPER=en_US.UTF-8;
LC_NAME=C;
LC_ADDRESS=C;
LC_TELEPHONE=C;
LC_MEASUREMENT=en_US.UTF-8;
LC_IDENTIFICATION=C"
can I change them in my bash profile? If yes which ones should be changed
and to what values, an example would greatly help.
