    This is standard IDNA2003 behavior. It is usually desirable because a) many
    German speakers are unsure about when exactly to use ß vs. ss, b) the
    spelling reform a few years ago changed the rules, and c) Switzerland does
    not use ß at all in German. This means that for most purposes it is
    counter-productive (and can be a security risk) to distinguish ß and ss.

    IDNA2008, an incompatible update, by itself does not map characters. UTS #46
    provides a compatibility bridge for both IDNA2003 and IDNA2008, and the ß
    behavior is an option there.
