<mapframe>: Couldn't parse JSON: Control character error, possibly incorrectly encoded

Some of the links are red and some are blue, but all the linked pages exist.

(NB. The rivers in the map are "way" objects in OSM. The missing rivers are "relations" of type "waterway" which are not supported. This is tracked in phab:T156433.)
