   CouchDB currently doesn't normalize json keys in the views, neither when updating the view or the start/end keys or key dicts when querying. Perhaps we should do it, but I think that's a larger decision to be made, as it would involve compatibility with existent views.
   
   CouchDB relies on unicode comparison only (`less(A,B) -> -1 | 0 | 1`). That function is used on each shard as base BTree ordering function, and used in the coordinator (fabric) when merging results. The primary issue that previously there was a subtle difference in how the functions worked on each shard vs how it works in the coordinator.
