A "share" feature for replies

On the right most of the reply header (too the right of the edit button), there should be a “share” button, that copies the link to that exact reply. I am unsure what symbol should be used, as all the ones I thought were good aren’t in unicode and therefor would require more coding.

This feature would allow non-staff/not-the-writer-of-the-reply to get a link to the reply; and would allow staff/writers-of-the-reply to share it quicker.
