‘Hauſtür’ – assuming it is intended to be the door of a house – is wrong in the
first place. The round s is used at the end of words within compounds.
The rule of thumb: for native words, if pronounced [z] or [ʃ], use the round s;
if [s], use the long s. (Non-native words were usually set by printing them in
Antiqua anyway.)
