在 utf-8 上转义重音字符 json

Question

下面的代码产生这个输出：

{"x": "Art. 120 - Incapacità di intendere o di volere"}

我需要更改为这个，我想我必须更改一些编码但我不知道是什么：

{"x": "Art. 120 - Incapacit\u00e0 di intendere o di volere"}

代码：

string label = "Art. 120 - Incapacità di intendere o di volere";
JObject j = new JObject();
j.Add(new JProperty("x", label));
string s = j.ToString();
Encoding encoding = new UTF8Encoding(false);
string filename = @"c:\temp\test.json";
using (FileStream oFileStream = new FileStream(filename, FileMode.OpenOrCreate, FileAccess.Write))
    {
    using (StreamWriter oStreamWriter = new StreamWriter(oFileStream, encoding))
    {
        oStreamWriter.Write(j.ToString());
        oStreamWriter.Flush();
        oStreamWriter.Close();
    }
    oFileStream.Close();
}

像别人说的，你要用StringEscapeHandling.EscapeNonAscii

using System;
using System.IO;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

public class Program
{
    public static void Main()
    {
        string label = "Art. 120 - Incapacità di intendere o di volere";
        JObject j = new JObject();
        j.Add(new JProperty("x", label));
        string s = j.ToString();

        var sr = new StringWriter();
        var jsonWriter = new JsonTextWriter(sr) {
            StringEscapeHandling =  StringEscapeHandling.EscapeNonAscii
        };
        new JsonSerializer().Serialize(jsonWriter, j);

        Console.Out.WriteLine(sr.ToString());
    }
}

产出

{"x":"Art. 120 - Incapacit\u00e0 di intendere o di volere"}
