Yup, you are right. I just discovered another post in this newsgroup. 
This seems to have worked:
M-x prefer-coding-system RET utf-8 RET
which is from:
http://groups.google.ca/group/gnu.emacs.help/browse_thread/thread/49787de21a638740/d3fdc305681db276?lnk=st&q=%22%5C200%5C230%22+emacs&rnum=2&hl=en#d3fdc305681db276


So, do I need to use the above command everything or is there a problem 
with the way emacs treats various locales? I have:
$> set | grep -i lang
LANG=en_CA.UTF-8
LANGUAGE=en_CA:en_US:en_GB:en
