Exported JSON cannot be loaded

It looks like the exported JSON has an encoding problem.

Suppose you are extracting http://en.wikipedia.org/wiki/Category:Programming_languages_created_in_the_1940s

This gives you JSON like this:

[{"id":1,"title":"Programming languages created in the 1940s","level":0,"transitivePages":1,"pages":1,"transitiveSubcategories":0,"parentCategories":0,"subcategories":0,"type":"Category"},{"start":1,"type":"ContainsPage","end":2},{"id":2,"title":"Plankalk<9F>l","type":"Page"}]

Upon loading in say Python you get this:

> > > import json
> > > jsonfile = open("bug.json", 'rb')
> > > cgraph = json.load(jsonfile)
> > > Traceback (most recent call last):
> > >   File "", line 1, in
