How do I preserve special characters when writing XML with XDocument.Save()?

Question

My source XML has the copyright character in it as ©. When writing the XML with this code:

var stringWriter = new StringWriter();
segment

It appears that UTF8 won't solve the problem. The following has the same symptoms as your code:

MemoryStream ms = new MemoryStream();
XmlTextWriter writer = new XmlTextWriter(ms, new UTF8Encoding());
segmentDoc.Save(writer);
ms.Seek(0L, SeekOrigin.Begin);
var reader = new StreamReader(ms);
var result = reader.ReadToEnd();
Console.WriteLine(result);

I tried the same approach with ASCII, but wound up with ? instead of ©.

I think using a string replace after converting the XML to a string is your best bet to get the effect you want. Of course, that could be cumbersome if you are interested in more than just the @copy; symbol.

result = result.Replace("©", "\u0026#x00A9;");
