"?" character creating issues with json parsing or receiving from WebView.

WebView console:
sending json to Unity: {"name":"abc","response":{"id":"abcid","answers":[{"elm":"ordering_1","type":"sequence","markType":"item","value":["watch","I","films"],"verification":[0,0,1]},{"elm":"ordering_2","type":"sequence","markType":"item","value":["pictures","paint","I","don't"],"verification":[0,0,0,0]},{"elm":"ordering_3","type":"sequence","markType":"item","value":["you","music?","listen","Do","to"],"verification":[0,0,1,0,0]},{"elm":"ordering_4","type":"sequence","markType":"item","value":["on","you","excursions?","Do","go"],"verification":[0,1,0,0,0]}],"act_id":"xyz","score":3}}

Debug value in Unity:
"{\"name\":\"abc\",\"response\":{\"id\":\"abcid\",\"answers\":[{\"elm\":\"ordering_1\",\"type\":\"sequence\",\"markType\":\"item\",\"value\":[\"watch\",\"I\",\"films\"],\"verification\":[0,0,1]},{\"elm\":\"ordering_2\",\"type\":\"sequence\",\"markType\":\"item\",\"value\":[\"pictures\",\"paint\",\"I\",\"don\'t\"],\"verification\":[0,0,0,0]},{\"elm\":\"ordering_3\",\"type\":\"sequence\",\"markType\":\"item\",\"value\":[\"you\",\"music?%22,%22listen%22,%22Do%22,%22to%22],%22verification%22:[0,0,1,0,0]},{%22elm%22:%22ordering_4%22,%22type%22:%22sequence%22,%22markType%22:%22item%22,%22value%22:[%22on%22,%22you%22,%22excursions?%22,%22Do%22,%22go%22],%22verification%22:[0,1,0,0,0]}],%22act_id%22:%22xyz%22,%22score%22:3}}"

'?' character after "music" seem to be creating issues.

Start by comparing the WebView console payload with the debug value received in Unity, focusing on the transformation around the question marks and encoded quotes. Reproduce the message with the supplied JSON and verify that the received value remains valid JSON with the original question marks preserved.
