Character encoding

For this piece of code:

String content = String.Empty;
ListenerStateObject state = (ListenerStateObject)ar.AsyncState;
Socket handler = state.workSocket;

int bytesRead = handler.EndReceive(ar);

if (bytesRead > 0)
{
   state.sb.Append(Encoding.UTF8.GetString(state.buffer, 0, bytesRead));

   content = state.sb.ToString();
   ...

I'm geting 'Ol?' instead of 'Olá'

What's wrong with it?

Are you sure that the stream is actually utf-8 encoded? Try inspecting the raw bytes in the buffer before encoding (there should be 4) and see what the actual byte values are.

Most likely it's the wrong encoding.

But if you use this code to receive blocks of bytes (split by a protocol) you will have a serious flaw: there is no guarantee that the block were independently encoded.

Simple case: the boundary of 2 blocks cuts through a multi-byte encoded char.

Best solution: Attach a TextReader to your Stream.

Are you outputting the result into something that understands 'complex' encoding?
