eszett.exe ~2.3MB
When typing German on non-German keyboards, it's not entirely clear how to enter the "ß" character. There's
charmap.exe and Win+"." but those are all pretty indirect.
Install eszett.exe to map the combination of Ctrl, Alt and "S" (or 'AltGr' if your keyboards has it, and "S") to enter a "ß" character.
