IMAP Sort in c#

Question

How can I send this command:

var command = "SEARCH CHARSET UNICODE BODY {5}";
var command2= "icône";

to an imap server with c#

I am actually trying to use something like this:

 this._sslStream.Write(System.Text.Encoding.UTF8.GetBytes(stamp + ((stamp.Length > 0) ? " " : "") + command + "\r\n\r\n"), 0, stamp.Length + ((stamp.Length > 0) ? 1 : 0) + command.Length + 2);

I'm blocked, without accent it is ok, with accent, I get no answer

Answer 1

当编码为UTF-8时， "icône"占用6个字节，而不是命令（ {5} ）中指示的5个字节。
