Write HTML string in JSON
You can, once you escape the HTML correctly. This page shows what needs to be done.
If using PHP, you could use json_encode()
Hope this helps :)
You should escape the characters like double quotes in the html string by adding "\"
eg: <h2 class=\"fg-white\">
Just encode html using Base64 algorithm before adding html to the JSON and decode html using Base64 when you read.
byte[] utf8 = htmlMessage.getBytes("UTF8");
htmlMessage= new String(new Base64().encode(utf8));
byte[] dec = new Base64().decode(htmlMessage.getBytes());
htmlMessage = new String(dec , "UTF8");
