Technically these are all still Latin leters, just that they’re written in a weird way that evolved from middle-aged Gothic handwriting as opposed to Latin directly which was the case with English cursive. This style of writing, along with the print-oriented 𝔣𝔯𝔞𝔨𝔱𝔲𝔯, was abandoned for the Latin equivalent by the Nazis for logistical reasons in 1941.

I’m not sure about the first and second "s"es, but the third is an “ß” (es and zet) that is still used for a sharp s sound following a long vowel… it’s still in use, for example in “Straße” (street). The second “t” is a “tz” which is also atill in use in words like Katze (cat).
I expected ß but then the extra letters kept going lol
The first one is a long s, the second is the “normal” s.
