Thanks for the reply, although I still can't get it to work. I upgraded to
aquamacs 1.8 and also set the locale in bash as follows,

$ locale
LANG="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_CTYPE="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_ALL="en_GB.UTF-8"

but I still get the same error. Note that I couldn't work out how to test
emacs in the terminal (M-x R didn't do anything), but I guess it's the same
settings for aquamacs.

Is there some kind of (set-language-environment 'UTF-8) thing to place in my
.emacs file?


Best regards,

baptiste
