Change emojis' font

Here: #47 (closed) we wanted to change the emojis' library.

After a few discussions, it appears it would be best to just change the font, to improve current situation (emojis' being not so friendly looking).

mentioned in issue #47 (closed)

changed the description

@jbpasquier anything to add to this issue, any technical challenge? do we know which font we want to use?

Need investigation at first.

Finding the right font will take much more time than integrate it. Integration should not be longer than - let say 5 minutes of dev and 10 for testing it well? :-)

Okay! Soo is the choice of font something for Sophie? Or not related at all to UX/UI?
