mosquitto_sub -F "%j" not encoding correctly

[benbarbour]

Steps to Reproduce

1. echo -n '"DATA"' | mosquitto_pub -s -r -t myTopic
2. mosquitto_sub -t "myTopic/#" -F "%j" -W 1

Expected Output:

{
 "tst": 1554139867,
  "topic": "myTopic",
  "qos": 0,
  "retain": 1,
  "payloadlen": 6,
  "payload": "\"DATA\""
}

Actual Output:

{
 "tst": 1554139867,
  "topic": "myTopic",
  "qos": 0,
  "retain": 1,
  "payloadlen": 6,
  "payload": "\u0034DATA\u0034"
}

When I decode the actual output's payload using jq I get an error. When I try to unescape it (using a few different tools) I get "4DATA4".

Thanks very much, this was a silly mistake. It will be in 1.6 shortly.
