'Jackson JSON parser invalid utf-8 start byte

I'm trying to parse the following JSON and I keep getting a JsonParseException:

{
   "episodes":{
      "description":"Episode 3 – Oprah's Surprise Patrol from 1\/20\/04\nTake a trip down memory lane and hear all your favorite episodes of The Oprah Winfrey Show from the last 25 seasons -- everyday on your radio!"
   }
}

also fails on this JSON

{
   "episodes":{
      "description":"After 20 years in sports talk…he’s still the top dog!  Catch Christopher “Mad Dog” Russo weekday afternoons on Mad Dog Radio as he tells it like it is…Give the Doggie a call at 888-623-3646."
   }
}

Exception:

Solution 1:[1]

The character at column 33 is –, and the reason this would be the byte 0x96 is that the file is physically encoded as Windows-1252. You need to save the file in UTF-8, windows-1252 is not a valid encoding for json. How to do this depends on what text editor you are using.

See JSON RFC:

  1. Encoding

    JSON text SHALL be encoded in Unicode. The default encoding is
    UTF-8.

I have also faced similar issue. open your json in Notepad ++, then in encoding drop down select as UTF-8. and save the text to other file. doing this resolved the issue.

Solution 3:[3]

Everything mentioned here I tried and none solved my issue, so I manually typed the payload and it solved my issue.
