Locale case change not working

[Clodoaldo]

When using unicode the case change works:

>>> print u'É'.lower()
é

But when using the pt_BR.utf-8 locale it doesn't:

>>> locale.setlocale(locale.LC_ALL, 'pt_BR.utf-8')
'pt_BR.utf-8'
>>> locale.getlocale()
('pt_BR', 'utf')
>>> print 'É'.lower()
É

What am I missing? I'm in Fedora Core 5 and Python 2.4.3.

# cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
