I'm trying to remove all the whitespaces from the NSNumberFormatter string. It seems it adds Unicode 160 as a whitespace instead of Unicode 32 and then String's stringByReplacingOccurrencesOfString doesn't work. Is this correct behavior and how should I remove the whitespaces?let formatter = NSNumberFormatter() formatter.locale = NSLocale(localeIdentifier: "fi") formatter.numberStyle = .CurrencyStyle formatter.currencyCode = "EUR" formatter.currencySymbol = "" let value = formatter.stringFromNumber(1234) ?? "" //"1 234,00 " let trimmed = value.stringByReplacingOccurrencesOfString(" ", withString: "") // "1 234,00 " let chars = value.utf16.map { $0 } chars // [49, 160, 50, 51, 52, 44, 48, 48, 160]
