When i install python-cjson 1.0.5-1 from Fedora 8 package i get this error:

>>> cjson.encode('é', encoding='utf8')

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
TypeError: encode() takes no keyword arguments

But when installed from source it works:

>>> cjson.encode('é', encoding='utf-8')
'"\\u00e9"'
