And if it might not be present, then

  "en-GB": doc['en-GB'] || null,

... etc
(otherwise you will get 'undefined' and couch-js falls over when trying to
serialize it)

You can of course just do
  emit(doc.default, doc);

to get the whole document, or

  emit(doc.default, null);

which emits no value, but since you have the docid you can query with
?include_docs=true

HTH,
