sweden does something similarly weird. we don’t have a currency symbol (unless you count “kr”) so the standard way to write a price is “20:-”, which used to be “20kr, 0öre”, with the colon as the decimal separator and the line added so you couldn’t write in another value, but then we switched decimal separator for currency to “,” and “:-” just became the symbol for “money”.
you even occasionally see abominations like “19,90:-”…
oh me too we should hang out
