 |I think it would be adequate and sufficient to replace the words ”normal
 |mapping” to “default mapping in Unicode”. This would clarify that such a
 |mapping is what Unicode specifies as the default. Whether it is the “normal
 |mapping” depends on how “normal” is defined.

Sigh, maybe i was mistaken with Switzerland, says wikipedia.  I am
too lazy to get up and look into the Duden.
Wikipedia says anyway:

  Die ersten Vorschläge, für das Eszett im Antiquasatz eine
  Majuskelform einzuführen, erschienen 1879 in der Fachzeitschrift
  Journal für Buchdruckerkunst.

First proposals for uppercase 1879 in a prof.-mag.

  Im Duden von 1925 wurde der Bedarf an einer Normierung eines großen Eszett formuliert:

    „Die Verwendung zweier Buchstaben für einen Laut ist nur ein
    Notbehelf, der aufhören muss, sobald ein geeigneter
    Druckbuchstabe für das große ß geschaffen ist.“

In 1925 they said it is only an expedient to use two letters, that
has to stop as soon as possible.

And what is normal.  I think in Psychology they already changed
by the beginning of the 90s to say something like "normal is when
the person can live with it", or something similar.
That is better than modern times, where i personally surely cannot
live with that bullshit mountain of lies and other crap.  (Sorry.)
I have never used uppercase SZ myself, all my life.

Ciao,
