ñ character in ASP.NET Core 3.1 http header

Question

I have a ASP.NET Core 3.1 web server and I'm receiving post requests like this:

[HttpPost("/api/loginweb")]
        public IActionResult loginWeb([FromHeader(Name = "usuario")] String usuario, [FromHeader(Name = "pass")] String pass)
        {

The problem I have is sending the ñ character on a header:

But, when I receive it I get:

You can right-click barñfoo in postman, choose EncodeURlComponent option, and then when the data of usuario is received, use HttpUtility.UrlDecode() method to get the string containing special characters.

 [HttpPost("/api/loginweb")]
        public IActionResult loginWeb([FromHeader(Name = "usuario")] string usuario, [FromHeader(Name = "pass")] string pass)
        {
            usuario = HttpUtility.UrlDecode(usuario);
            return Ok();
        }

Here is the process to test:

Well, yes, I finnally encoded it on the client side as in my case it depends on me, but I didn't want to do that, I just want to be able to make the API understand the encoding, like in any other languges and frameworks... I see your answer like a workaround. Maybe it is imposible and your approach is the best one... – Carlos López Marí Oct 05 '20 at 06:20

@CarlosLópezMarí,Sorry, this is the solution I have found so far. If allowed, putting it in the body rather than header and passing it will not cause this issue. – LouraQ Oct 06 '20 at 09:01
