      Write('你好');

when I open in browser, it display ??.

how to  display chinese in browser?

You can not send Unicode characters out directly with the Write method. You need to properly encode your Unicode content. If you are using UTF-8 encoding, you can do it by using the function Utf8Encode (returns encoded String) or Utf8EncodeEx (returns encoded byte array).

For example:

with Sender as TRtcDataServer do
    if Request.Complete then
      begin
      WriteEx( Utf8EncodeEx( '你好' ) );
      end;

Another way would be to use HTML escape sequences with character codes. In that case, the encoding of your HTML page is not important.
