The IMAP server replied to the 'SEARCH' command with a 'NO' response: Character set not supported for search

I get this error when I use the search command with special charachter in searchPhrase like "سلام" it works fine in other cases. I've also tried encoding to UTF-8. there is no error then but it doesn't give back any result.

var uids = Client.Inbox.Search(SearchQuery.SubjectContains(searchPhrase));

any suggestion?

I just tested this on GMail using MailKit and this is what I get:

S: A00000006 OK [READ-ONLY] INBOX selected. (Success)
C: A00000007 UID SEARCH RETURN () CHARSET UTF-8 SUBJECT {8+}
C: سلام
S: * ESEARCH (TAG "A00000007") UID
S: A00000007 OK SEARCH completed (Success)

What is the error? Seems to work fine for me (other than the fact that I obviously don't have any messages with that string in the Subject header).

Here is my little test program:

using System;

using MailKit.Net.Imap;
using MailKit.Search;
using MailKit;
using MimeKit;

namespace GMailSearchTest {
    class Program
    {
        public static void Main (string[] args)
        {
            using (var client = new ImapClient (new ProtocolLogger (Console.OpenStandardOutput ()))) {
                // For demo-purposes, accept all SSL certificates
                client.ServerCertificateValidationCallback = (s,c,h,e) => true;

                client.Connect ("imap.gmail.com", 993, true);

                // Note: since we don't have an OAuth2 token, disable
                // the XOAUTH2 authentication mechanism.
                client.AuthenticationMechanisms.Remove ("XOAUTH2");

                client.Authenticate ("[email protected]", "xxx");

                client.Inbox.Open (FolderAccess.ReadOnly);
                client.Inbox.Search (SearchQuery.SubjectContains ("سلام"));

                client.Disconnect (true);
            }
        }
    }
}
