How can special characters be sent in a request body without conversion by using Unicode code point?

edit

To send special characters in a request body without conversion, you can use Unicode code points instead of the actual characters. Unicode code points are numbers that represent each character in the Unicode standard.

To use Unicode code points in a request body, you need to format them properly. You can do this by adding a backslash followed by the letter "u" and the four-digit code point. For example, the code point for the letter "é" is U+00E9, so you would represent it as "\u00E9" in the request body.

Here's an example of how to use Unicode code points in a JSON request body:

{ "name": "\u00E9milie", "email": "emilie@example.com" }

In this example, the name field contains the special character "é", represented by its code point. When the server receives this request, it will treat the code point as the actual character, without any conversion or encoding.
