Unidentified character

This looks like it might be a Chinese or Japanese character. I wish I knew what it means - and why it’s here!

“Our character is what we do when we think no one is looking”
(H Jackson Brown, Jr).

“You can tell alot about a fellow's character by his way of eating jellybeans”
(Ronald Reagan).

“Nothing shows a man's character more than what he laughs at”
(Johann Wolfgang von Goethe).
