Since wands always seemed pretty essential inHarry Potter, Rowling took to Twitter to clarify some fan queries.

Shes done a lot to promote #HeForShe, a U.N. campaign for international gender equality and solidarity.

The new emoji lives up to the organizations name, combining the traditional symbols for male and female.

At this,Rowling salutedher real-life Hermione, calling her an inspirational woman.

Watson responded in kind.

Watson wasnt the only Hermione to get Rowlings support this week.

Rowling responded to the tweet and got into a fun back-and-forth.

To everyones surprise, she accepted the librarys invitation and did pop by for a visit.
