@petrilaarne wikipedia says in Sweden a ✓ is often used for "incorrect". No mention of % though - that's interesting! It feels like a tricky symbol to draw, which matters when you're doing a lot of marking!
@christianp The Wikipedia page for ”check mark”, and apparently Unicode, contain the correct form of %; not the literal percent sign (they look the same in my handwriting). Still, I feel that the English version has largely killed off that symbol.
