I'm working on cleaning up my
Essays 1743 font a bit. I found that, for the Unicode character "MODIFIER LETTER CAPITAL REVERSED E", I had rotated the E 180°. I wasn't sure that was the proper interpretation of "reversed", so I Googled it. The first hit was ambiguous, because it was demonstrating with a very simple font, in which a rotated E would've looked the same as a mirror image.
I then looked at
the third hit, which gives examples from 5 free fonts...all of which are mine. Not useful. :-)
(I wound up deciding that "reversed" meant mirror image, both because, duh, it does, and because the first example showed other reversed characters which were clearly mirror images.)
