Is it necessary to escape special characters in JS data being posted to the service layer in the request payload?

My task involves conducting a sanity check on how our application is sending data to the service layer.

Consider the following scenario:

The frontend sends this JSON with the content-type: application/json

{
  "description":"\n  das!!!'/.xtest",
  "topic":"test"
}

From a security standpoint, should special characters in the JSON request payload be escaped before transmission?

What is the best practice for sending or updating JSON with special characters in general?

I have searched extensively for answers but have not found a recommended or widely accepted standard.

Your input would be highly appreciated!

When sending a JSON request payload, should special characters be escaped for security reasons?

Not necessary.

What is the recommended approach for sending JSON with special characters in general?

There is no need for additional measures. As long as the JSON data is valid, it is already appropriately handled for escaping.

Of course, caution should still be exercised when processing any input from clients, including JSON content, to prevent vulnerabilities such as cross-site scripting attacks.
