As Dmitry mentioned earlier json-encode in 25.1 produces multibyte strings and makes it easier to hit this bug when consuming JSON API's. There are three parties that are suspicious: 1) JSON API server 2) JSON.el 3) URL. It took me a while to realise it's URL's fault IOW the bug isn't easy to debug. This is somewhat related to changes brought in by 25.1. Leo
