In both black letter and antiqua texts, two forms of the lower case letter s can occur: the long-s (Å¿, U+017F, LATIN SMALL LETTER LONG S) and the round s (s, U+0073, LATIN SMALL LETTER S). They are not distinguished in the transcription. They are recorded as round-s.

Original Explanation transcribed text
A long-s followed by a s is in both cases transcribed as round-s. dass
A long-s followed by a z is transcribed as round-s + z. hausszen
The ligature long-s + z is transcribed as ß. daß
