Decoding Multi Level Json

"{\"topic\": \"dummy_topic\", \"msg\": \"{\"fruit\":\"apple\",\"dish\":\"apple-pie\"}\"}" → This does not work

iex(1)> Jason.decode("{\"topic\": \"dummy_topic\", \"msg\": \"{\"fruit\":\"apple\",\"dish\":\"apple-pie\"}\"}")
{:error,
 %Jason.DecodeError{
   data: "{\"topic\": \"dummy_topic\", \"msg\": \"{\"fruit\":\"apple\",\"dish\":\"apple-pie\"}\"}",
   position: 35,
   token: nil
 }}

"{\"topic\": \"dummy_topic\", \"msg\": {\"fruit\":\"apple\",\"dish\":\"apple-pie\"}}" → This works

iex(2)> Jason.decode("{\"topic\": \"dummy_topic\", \"msg\": {\"fruit\":\"apple\",\"dish\":\"apple-pie\"}}")
{:ok,
 %{
   "msg" => %{"dish" => "apple-pie", "fruit" => "apple"},
   "topic" => "dummy_topic"
 }}

The only difference between the strings is

"{\"topic\": \"dummy_topic\", \"msg\": *\"*{\"fruit\":\"apple\",\"dish\":\"apple-pie\"}*\"*}"

The escape sequences causing problem are wrapped in *

Those two escape sequences if removed , makes it work fine.

Is there a way with Sigils I can choose to not have those escapes ? or I have to do string manipulation to have it working ?
