How do they pronounce D-flat?

While we're at it, are Dis, Fis, Gis and Ais the other sharps?

I know people who say it jokingly. Never met anyone who meant it seriously.

If only there were a convenient way to enter rare characters on ordinary keyboards. There would be no more confusion between the musical note C𝄰 and the programming language C#. Or maybe the language would be called C𝄱 instead, confusing everyone to no end. (Those are three different symbols.)

EDIT: It appears that HN eats the "music sharp sign" character, but not "musical sharp up" or "musical sharp down".
