Would you approve of a regular character in the English alphabet as the standard currency symbol for BTC?
Please reconsider further promoting this character - I know we're only about 90 million people but I would really rather not have a few dozen BTC symbols spread over all existing German texts...
Yes, it's used in German. The whole reason I know how to type ß in the first place, is that my family is German. I've asked several of them what they think of the use of ß for bitcoins. None of them have any problem with the idea. (And now two of my aunts and one of my cousins wants bitcoins...)
There's no ambiguity between the use of ß as a currency symbol with numbers, and the use of it in written German, whether you are using prefix or postfix notation.
