The client is another Zope instance that uses the Zope provided
I'm familiar using this one but it's the first time I sent non ascii chars

I'm trying to hack the stuff to have a view to the marshalled xml.
I'm just using the standard API...
server = xmlrpclib(http://some.server.net/)
x = server.doStuff(a, b, c)
I dunno how to mention the encoding to be used for strings (any of a, b, or
c) to have the stuff correctly marshaled and transmitted to the server.
Otherwise, I could "base64" those texts for the transport. and mention the
charset as a parameter.
Do u thing this may be a solution ?

Of the client side provided texts.

Ah OK, I gonna try this one...
# Client side (external method)
charset = 'iso-8859-1'
# Setting params
a = unicode(a, charset)
b = unicode(b, charset)
# Making request
server = xmlrpclib.Server("http://some.webservice.net/")
resultstring = server.doStuff(a, b).encode(charset, 'replace')
# Server side handler (TTW python script)
charset = 'utf-8'
a = a.encode(charset, 'replace')
b = b.encode(charset, 'replace')
# Do the stuff
return unicode(stuff, charset)
