WhatsApp put an emoji their URL

Emoji characters already appeared in DNS, but now also in an URL. And Google shows them perfectly what makes me wonder if all parts of their code base are ready to handle this correctly or that it is an incident.


So the big question is when marketeers and/or criminals start to use this to trick people into clicking on links. Also how do other systems like a CRM are going to handle this correctly.
