I don't know if this is the place for this but it's Microsoft-related because it's Windows-related...
I've been a Windows fanboy for years, (and I was a DOS fanboy before that...back in 1991 I was, simultaneously a DOS AND Windows fanboy!) but, until today, I never knew that a superscript was a valid character in a Windows file name.
Since long file names were introduced ie Windows 95, I've never seen a superscript in a file name and it would never occur to me to add one because you can't get one directly from the keyboard.
