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’ve had to read a few old German documents for personal genealogical research and good god, the handwritten words were hard to make out. Spent like 20 minutes just trying to read the phrase “ein und funfzig” (51, as in 1851). Someone else who’d read those documents completely misread them and listed his birthyear 20 years later than it should be, implying he was a 13 year old boy when he married a 30-something year old woman.
