UTF-8. french PO file, problem with august : Aôut.

[coulix]

Hello,
Django.po in french locale has
#: utils/dates.py:28
msgid "Aug."
msgstr "Aôut"

The file is encoded in UTF-8 (which is good).
On my website which have setting fr-fr i do
le {{ r.pub_date|date:"j M Y" }},
and get e 18 Ao? 2006.

Ao? instead off Aôut !
see it:
http://www.cefinban.net/recettes/poissons-et-crustaces/picots-kanaks-sauce-grand-coude_kinoux/

Page encoding is set to utf-8 so i dotn understand why only the
rendered Aôut.
All others : é ô è ect.. wich are part of the html, (not generated
by date function) are fine.
Help please :)
Otherwise an article was in a new caledonian news paper about the
website !. Thats what happen when you live on a 200k people island. It
is not going to bring a lot of django user tho.
