Hi all,
I've started to use spyne 2.9.3 and stumbled upon this: when I use French
characters in the docstring of a function, I get an "AssertionError" when I
try to connect to the service[0]:
>>> from suds.client import Client
>>> c = Client('http://localhost:7789/?wsdl')

ASCII, no NULL bytes or control characters

As far as I am concerned, I produce a lot of code intended for French
speaking maintainers; therefore my docstrings will contain
quite a lot of specific characters like 'é' , 'ê', 'ï', ...
In order to make it work, I modified spyne/interface/wsdl/wsdl11.py like
this:
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
(line 346)
documentation.text = unicode(method.doc)
Of course, the result is the same when just surrounding the docstring
with unicode(). But it felt wrong to me.
Have you got any idea why I get this encoding issue?
Regards,

[0] I use the example at
https://github.com/arskom/spyne/blob/master/examples/helloworld_soap.py
; just added a special French character in the docstring
