I need to understand if this is a bug or if it is the expected behaviour
and I'm doing something wrong.
I have two web2py applications. One of them implements an XMLRPC
webservice, and the other one consumes it.
All the controllers (in both applications) have this first line:
# -*- coding: utf-8 -*-
One of the applications connects to the webservice to call a specific
function, and it needs to pass some string arguments:
def make_the_call():
from xmlrpclib import ServerProxy
service = ServerProxy(webservice_url)
data = {
'title': 'áéíóú',
'detail': 'Detail with special characters like ñ or Ç'
}
service.add_content(data)
The application that implements the webservice:
from gluon.tools import Service
service = Service()
def call():
return service()
def add_content(data):
db.content.insert(
title=data.get('title'),
detail=data.get('detail')
)
return {'success': True}
But the sentence service.add_content(data) fails with this error and
traceback:
Traceback (most recent call last):

raise Fault(**self._stack[0])
Fault: <Fault 1: "<type 'exceptions.UnicodeEncodeError'>:'ascii' codec can't
encode character u'\\xe1' in position 1: ordinal not in range(128)">
To make it work, I need to reload sys and set default encoding in the
add_content() method of the webservice:
def add_content(data):
import sys
reload(sys)
sys.setdefaultencoding('utf8')
db.content.insert(
title=data.get('title'),
detail=data.get('detail')
)
return {'success': True}
After that, it works ok.
But here is the weird part: after having made one successfull call to the
webservice method, I can remove the lines where I reload the sys, and it
keeps working ok. But if I reload uwsgi, it starts throwing error again.
Anyway, I've read that reloading sys is not a good practise at all. So I'm
pretty lost. I presumed that I could add "# -*- coding: utf-8 -*-" and
forget about the encoding problems.
What should I do?
