JSON encoding - String contains control character

[Community Alums]

Morning All,

I'm working on an integration and for some reason am having issues with JSON encoding:

I have to JSON encode the description, short description and work notes when sent. I'm getting a catch error of String contains control character. Below is the description that's tripping it up and the payload being sent, any suggestions are appreciated:

Description:

This is a test description Please ignore this WO request

&
"
'
< 
>

Payload (some data redacted):

{
    "Header": {
        "TransactionID": "INC2072276-2021-09-16 09:22:14",
        "USERID": "#####",
        "SourceSystem": "#####",

    },

            "Caller": {

                "LastName": "Brown",

                    "AreaCode": "###",
                    "PhoneNumber": "####"
                }
            },

                    "Type": "General"
                }]
            },
            "attribute3": "#####"
        }
    }
}

try with JSUtil.escapeText(String) and then serialize

Thank you, swapped the encode with this and now it works perfectly.
