I have a problem during the serialization with data modified during deserialization (i dont think its the problem )

some \u char are not correctly transformed...and i dont see how to fix that.. even with a global encoder....

See my comments about PROBLEM and NO PROBLEM

CodePudding user response：

Can you handle it with the below code?

var response = "Željko Cvijetić";
var jsonSerializerSettings = new JsonSerializerSettings {
    StringEscapeHandling = StringEscapeHandling.EscapeNonAscii
};
var json = JsonConvert.SerializeObject(response, jsonSerializerSettings);

And using System.Text.Json

JsonSerializerOptions JsonSetting = new JsonSerializerOptions();
jso.Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping;

var s = JsonSerializer.Serialize(response, JsonSetting);
