@schratze so in Russian lowercase handwritten "i" looks like Latin "u", "p" looks like Latin "n", "t" looks like Latin "m", and "sh" looks like upside-down "m".
But in cursive, all these distinctions are lost, the only distinction left is the number of vertical bars (two for "i" and "p", three for "sh" and "t"). And there are no boundaries between letters either, so e.g. in a word "кипишит" ([3rd person] is making a fuss), you just get, depending on the writing style, "к" + basically a very long Latin "m" with 14 vertical bars. Good luck with even figuring out how many letters are in these 14 bars!
