How to add HTML text into Books note field

How to add HTML text into Books note field

I would like to add HTML formatted text into the note field in a Zoho Books estimate.

I am creating the estimate in a function in CRM.

Adding <br> or \n  have no effect. The API will also just accept a string as parameters.


CRM Code:
response = invokeurl
[
type :POST
parameters:parameters.toString()
connection:"crm2books"
content-type:"application/json"
];

EDIT:

This works:

newLine = hexToText("0A");
string = "A" + newLine + "B";
