[Zope] illegal id chars?

Why is it that objects can't be created because the id chosen contains characters that aren't proper in urls? Spaces are allowed and converted to their hex values when you create an object. Why not do this with every illegal url character? I must me missing something here because this seems like this should have been one of the first things designed into Zope.
