Hello everyone.

I found a bug when trying to send email from keycloak to users with encoding against English.

For example, when I try to send Russian message with subject “Обновите вашу учётную запись” I see “????????????? ?????? ??????????? ?????” in my email.

I think you should update org.keycloak.email.DefaultEmailSenderProvider class with line

msg.setSubject(subject);

to

msg.setSubject(MimeUtility.encodeText(subject, "utf-8", "B"));

Thanks.
