Although, to be fair, a lot of these aren’t really consistent, even within the same country. I’ve seen both types of S and A around, though it’s the first time i see that weird G.
Honestly, most of the more complicated ones aren’t really used where i’m from at all. Like, if you’re really trying to be fancy, sure, i could see it, but the writing i see day to day is a lot more simplified. Whole point is to write fast anyway.
