Title: [ALT] Add a notebook option to keep non-ASCII characters

Alternative to #7064. I'm not a [huge fan](http://xkcd.com/1378/) of this approach, as I'm afraid it spread the configuration to both the notebook server and nbconvert. We could explicitly instantiate the JSONwriter in each place instead of importing write and read from the module.
