Has anyone used Emojis in CiviMail subject/body?
@laryn the short answer is that for this to work your database needs to be changed. CiviCRM by standard sets things to be utf8_unicode_ci. You will need to convert database to utf8mb4_unicode_ci to allow for Emojis and you would need to change the setNames call in CiviCRM to be utf8mb4 as per https://stackoverflow.com/questions/7814293/how-to-insert-utf-8-mb4-characteremoji-in-ios5-in-mysql
