(un)restrictedTraverse fails with unicode Strings as Path

[Christian Theune]

Zopes unrestrictedTraverse function from OFS.Traversable splits the given path, failing when it receives a unicode string.

Possible solution: (i don't like it, but it's easily implemented, and i am no unicode expert) cast the path string to a default python string

Ok, I did a bit more research on that and found the splitting beeing the problem. Line 78 of Traversable.py tells us, that type(u"asdf") is not a StringType and so it is only converted into a list so that the NamespaceStack looks like [u"asdf"].

Another hint: string.split(u"asdf") won't work too. But u"asdf".split() works fine.

At the moment i can't create a patch, as I don't know how to make a good use of checking for subclasses of string, because strings and unicode strings don't have a __class__ attribute.

Just a little reminder. Could somebody please reject or accept this? Thanks.

Status: Pending => Rejected

If a string is expected than a string and not a unicode string
should be passed.
