What is this output-file for? You don't use that, in a json-controller
you just return the data-structures directly.
And the output file is your problem, you are creating representations of
unicode-strings, which are prefixed with that u.
So build the data you want, and then simply return it. Your code is to
messy to make a useful example (at least fast enough :))
