Ethan Lynn 6cf8dc6e56 Fix problems in unicode template support ...

If we use unicode as resource name or parameter,
we are likely to encounter unicode problems.
This patch aims to fix unicode problems, and
there are several things to be clear:

1. For the class wrap with six.python_2_unicode_compatible, in
python2 their original __str__ function will map to __unicode__,
and new __str__ function comes from __unicode__.encode.
So we should always return unicode in __str__() if wrap
with python_2_unicode_compatible.

2. python_2_unicode_compatible will not handle __repr__,
__repr__ should return str in all versions of python.
