Question: use special characters in email os high sierra
how do I insert special characters (for example the symbol for degree) in an email using apple email os high sierra. Previous answers regarding insertion of special characters say go to edit -> special characters, but "special characters" doesn't appear in the edit options. I used to be able to open character palette, but nothing happens when double clicking anymore.
