¹         º         »         ¼         ½         ¾         ¿         À         Á         Â         Ã         Ä

Å         Æ         Ç         È         É         Ê         Ë         Ì         Í         Î         Ï         Ð         Ñ         Ò         Ó

and AE copied    Æ    as text
then emoticons using hash codes:

😀         😁         😂         😃         😄         😅         😆         😇         😈         😉         😊         😋         😌         😍

and a copy & paste
