JsonObject unable to display symbol such as + < >

[tastynoob]

Very strange
the code:

JsonObject obj = new(){
  {"test" , "+"}
};
Console.WriteLine(obj.ToJsonString());

it's output

{"test":"\u002B"}

i found the symbols '+' '<' '>' all unable to display

if

JsonObject obj = new(){
  {"test" , "+="}
};
Console.WriteLine(obj.ToJsonString());

it's output

{"test":"\u002B="}

This is not a language question. You might want to ask the authors of JsonObject.

wait, I use "using System.Text.Json.Nodes", Isn't this build-in packet?

That would be https://github.com/dotnet/runtime.
