I haven't talked to German programmers lately. Is C# pronounced "Cis"?
EDIT: It appears that HN eats the "music sharp sign" character, but not "musical sharp up" or "musical sharp down".
EDIT: While C-Sharp is the correct pronunciation there were even books calling is Cis: https://books.google.de/books?id=srryCQAAQBAJ&lpg=PA1&dq=pro...
While we're at it, are Dis, Fis, Gis and Ais the other sharps?
