.parse(input, currency, strict: false, decimal_separator: decimal_separator_resolver&.call) ⇒ Money?

Parses an input string, normalizing some non-ASCII characters to their equivalent ASCII, then discarding any character that is not a digit, hyphen-minus or the decimal separator. To prevent user confusion, make sure that formatted Money strings can be parsed back into equivalent Money objects.
