What changed

“Unclear” values look valid in both formats, like 1.250: 1250 in Greek, 1.25 in US. They are read the way most of the other numbers in your paste are written. Currency signs (€ $ £), % and spaces between thousands are removed. Negatives can be -45,10, 45,10- or (45,10). Codes with leading zeros, dates and IDs with letters stay unchanged. Rounding is exact, with no floating-point errors.
