Opening utf-16 xml files in Visual Studio 2005

Hello,

If I edit the following xml file in Vistual Studio 2005 (File -> Open -> File...), it shows me nothing as the Error List tab contains the following error:
Error      1      Invalid token 'Text' at root level of document.      C:\Users\rich\Downloads\sample.xml      1      1      Miscellaneous Files

Here's the simple xml file.
<?xml version="1.0" encoding="utf-16"?>
<Report />

Changing the xml file to be utf-8 as follows:
<?xml version="1.0" encoding="utf-8"?>
<AssessmentReport />

allows VS to open the file correctly.

Why is this?  Please note that I am getting this xml file from a third party, so it's not really possible to change the utf-16 to utf-8 in practice.

I really don't understand why any XML needs any more than UTF-8 or ISO-8559-1 (1252) encoding.  I don't know of any way around this, other than changing the encoding.

Yeah, I agree... but the provider says that is the default output of whatever .NET process they are using to create the .xml.

I guess I am forced to keep editing / reading it with Notepad or Notepad++ instead of VS or MSIE...

If they are using XSLT transformation, the default is to use UTF-16 encoding, but you can override that.

Oh, really?   Can you tell me how to have them override that?  That will suffice as a solution...

I used to have code for that, but it got lost somewhere...

But, I believe that it is something like this:

http://social.msdn.microsoft.com/forums/en-US/xmlandnetfx/thread/6db1a7a9-6c3a-46ff-a696-0f04d7afbef5

XslCompiledTransform xslt1 = new XslCompiledTransform();
            xslt1.Load(reader1);

            XPathDocument doc1 = new XPathDocument(new StringReader(source));

            StringBuilder sb1 = new StringBuilder();

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.OmitXmlDeclaration = true;
            settings.Encoding = System.Text.Encoding.UTF8;
            XmlWriter xsltOutput1 = XmlWriter.Create(sb1,settings);

Turns out they could change it from utf-16 to utf-8 using your suggestion.
