PS: I did not know which forum to select to report this bug. My apologies.
I have received e-mail regarding post in forum thread to which I am subscribed to be notified by e-mail.
E-mail I have received is plain-text, not HTML, and an apostrophe ( ' ) character in my post was sent to me as an HTML entity:
'(ampersand followed by hash, number 39 and a semicolon)
This is rather low-priority cosmetic bug.
