Capturing output from standard io encoding?

Question

I'm piping the output of an app into my .NET app.

The encoding is somewhat strange. Letters ÅÄÖ shows up as ├Ñ ├ñ ├Â

I have tried to convert back and forth from various different encodings w/o any success. Anyone know how the string should be converted correctly here?

e.g. the documentation for the app says the output is UTF8, so I've tried this:

byte[] encodedBytes = Encoding.UTF8.GetBytes(theOutput);
var res = Encoding.Default.GetString(encodedBytes);

Which goves the incorrect result.

edit: code:

var processStartInfo = new ProcessStartInfo
{
   CreateNoWindow = true,
   RedirectStandardOutput = true,
   RedirectStandardInput = true,
   UseShellExecute = false,
   Arguments = a,
   FileName = path + "\\phantomjs.exe"
};

var process = new Process
{
   StartInfo = processStartInfo,
   EnableRaisingEvents = true
};

//capturing output here
process.OutputDataReceived += 
   (sender, args) => outputBuilder.Append(args.Data);

process.Start();
process.BeginOutputReadLine();
process.WaitForExit(20000);
process.CancelOutputRead();

Found the solution. You can set

   processStartInfo.StandardOutputEncoding = Encoding.UTF8;

This makes it output correctly.
