// Generally follows UNGEGN <http://www.eki.ee/wgrs/rom1_ar.pdf>
// Occasionally deviates in the direction of ISO 233 <http://homepage.mac.com/sirbinks/pdf/Arabic.pdf>

// b) with underdot instead of cedilla for letter like SAD, since

// While it could be done, we need to determine whether a prefix "al" could
// occur other than as the definite article (since no space is used).
