Unfortunately, emoticons are covered by Unicode surrogate pair characters, which are not supported correctly in the current version.

This will be fixed in the next release. If you have active support and you want to receive hotfix version right now, please let us know.

For list of available Unicode emoticons see and its representations in different systems visit https://apps.timwhitlock.info/emoji/tables/unicode.

To specify an emoticon just copy&paste from the list above:

var mail = new MailMessage();

or use the UTF-8 notation like this:

mail.Subject = "GRINNING FACE " + Encoding.UTF8.GetString(new byte[] { 0xF0, 0x9F, 0x98, 0x80 });

Hi Lukas,
I tried both of your suggestion on the current trial version  (2018-R2.1) but did get two question marks for the emoticon?
I don't think Rebex allow changing the charset of the header?
Many thanks,

The support for Unicode surrogate pair characters will be added in next release (2018-R3).

You can try trial hotfix version, which is available at  https://www.rebex.net/getfile/a547c27514914bfeb091a44ad7f850c4/RebexSecureMail-HotfixBuild6849-Trial-Binaries.zip
