UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES (UNGEGN)
The Conference,
Recognizing that modern practice has come to require the rendition of Arabic alphabet geographical names in terms of standard, that is, classical forms,
Recommends that Arabic-speaking countries provide as soon as possible complete documentation for all geographical names, including the provision of all vowels and the notation of unvowelled and double consonants by means of the Arabic diacritical marks such as vowel points, shaddahs, hamzehs and sukūns.
