Comment (by mbootsman):

 I think this needs some attention.
 Copying ans pasting an emoji from a website, or using a emoji keyboard
 breaks UX, as a widget is just not saved, and previous content is shown.

 User would need a notification that the emoji throws an error, or the
 emoji should be converted to the HMTL notation like &#1F90D;
 automatically.
