Current result on https://www.wikidata.org/w/api.php?format=json&formatversion=1&action=wbgetentities&sites=dewiki&titles=This+title+does+not+exist+%C3%A4%C3%B6%C3%BC

Current result on https://www.wikidata.org/w/api.php?format=json&formatversion=2&action=wbgetentities&sites=dewiki&titles=This+title+does+not+exist+%C3%A4%C3%B6%C3%BC

{"entities":{"-1":{"site":"dewiki","title":"This title does not exist äöü","missing":""}},"success":1}

formatversion=2 uses the UTF-8 encoding instead of the JSON string escaping for Unicode characters but not the modern JSON syntax like "missing":true instead of "missing":"".
