bug#30988: 25.3; Cannot input capital sharp S using the input method german-prefix

[Nichtmein Name <cgeek97@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 3317 bytes --]

 Steps to reproduce:
1) Launch emacs -Q
2) M-x set-input-method german-prefix
3) Type " (double quote) followed by S (capital s)

Expected behavior:
Emacs should insert ẞ, that is, a capital sharp S (which is an official
letter in Germany
as of 2017, see https://en.wikipedia.org/wiki/Capital_%E1%BA%9E )

Actual behavior:
Emacs inserts the text literally.
