what is the character encoding of vs2005/2008?

I use the program which is made by vs2008 C#.net to type the chinese character and then save to mssql database. I can successfully see the chinese in sql browser, but when I use php and using utf-8 to get the chinese back, and there is Mojibake. So, what is the charset of my web?

The encoding of the application Visual Studio is not the problem, Visual Studio is simply the IDE in which you create applications. If you're displaying non-English characters, then you should set the document's CharSet in the HTML. What have you set the current charset to?

I thought mssql cannot save chinese character or utf-8/big5 b4...I think it is wrong now.

My webpage using charset=utf-8:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Does anyone know?

Maybe start here: Understanding Encodings?
