Save all files in Visual Studio project as UTF-8

I wonder if it's possible to save all files in a Visual Studio 2008 project into a specific character encoding. I got a solution with mixed encodings and I want to make them all the same (UTF-8 with signature).

I know how to save single files, but how about all files in a project?

How do I change the default encoding in Visual Studio?

Now open one of your files in Visual Studio. To verify its saving as UTF-8 go to File > Save As, then under the Save button choose "Save With Encoding". It should choose "UNICODE (Save without Signature)" by default from the list of encodings.

Since you're already in Visual Studio, why not just simply write the code?

foreach (var f in new DirectoryInfo(@"...").GetFiles("*.cs", SearchOption.AllDirectories)) {   string s = File.ReadAllText(f.FullName);   File.WriteAllText (f.FullName, s, Encoding.UTF8); }

Only three lines of code! I'm sure you can write this in less than a minute :-)
