Tiniest Correction

Carl: What’s the alt code for a degree sign?
Me: Alt + 0176
Joe: Alt + 0186
Me: *narrows eyes* To charmap.exe!
Joe: Hm… Apparently Alt + 0186 is the masculine ordinal indicator and Alt + 0176 is the degree sign.
Me: Are they actually different?

Pretty easy to see at 400 point.

I think this is the narrowest margin by which I’ve every typographically one-upped someone.
