comparison genshi/core.py @ 915:9fafb35032a1 experimental-py3k
add support for python 3 to core genshi components (genshi.core, genshi.input and genshi.output):
* default input and output encodings changed from UTF-8 to None (i.e. unicode strings)
* Namespace and QName objects do not call stringrepr in __repr__ in Python 3 since repr() returns a unicode string there.
* track changes to expat parser in Python 3 (mostly it accepts bytes instead of strings)
