Arabs do not use Arabic digits. They use Hindi digits and Arabic digits are auxiliary (the same as Roman digits for us). But, in any case, all digits are written from left to right. This property indicates whether it is necessary to convert Roman digits (ASCII 0030h-0039h) to Arabic digits (Unicode 0660h-0669h or 06F0h-06F9h, depending on the ArabicDigitsType property). In each types of export the digits conversion can be set by their own property.
