 WordPress includes a `wp_json_encode()` method for dealing with non-UTF8
 strings before passing them to `json_encode()`.

 The standalone API handler doesn't have this available to it, and as such,
 doesn't handle JSON outputs for data containing non-utf8 data (which often
 occur within readme's and reviews).

 I would suggest we should just borrow `wp_json_encode()` and namespace it
 appropriately, or we could alternatively include a compat file for stand-
 alone instances when WordPress hasn't been included.
