This document provides a description of the IDN (Internationalized Domain Names) Language Table to be used by SaudiNIC the .sa TLD registry for the registration of Arabic language .sa domains. These are based on the recommendation of the Arabic Domain Name Pilot Project (www.arabic-domains.org).

Tashkeel (Diacritics) and Shadda
They are small singes that are usually put on top or under an Arabic letter for the purpose of correct pronunciation which may leads to a different meaning. Al-tashkeel is not a letter by itself but it is a mean to correctly pronounce a letter. It is not widely used except incase of the possibility of mispronouncing words that have the same letters but with different pronunciations, and hence having different meanings.
Therfore, Tashkeel and Shadda should not be supported in IDN, yet they can be supported only in the user interface, and stripped off at the preparation of internationalized strings (stringprep) phase.
Kasheeda or Tatweel (Horizontal Character Size Extension)
Kasheeda is not a letter. It is a horizontal line (like dash) used to lengthen the connection line between letters. It is used sometimes to enhance the display of Arabic words on screens or printouts.
Hence, Kasheeda (Tatweel) should not be used in IDN.
Character folding is the process where multiple letters (that may have some similarity with respect to their shapes) are folded into one shape. This includes:
With respect to the Arabic language, character folding is not acceptable because it changes the meaning of the words and it is against the simplest spelling rules.
Therfore, character folding should not be allowed.
In the Arab world, there are two sets of numerical digits used:
From U+0030 (Digit Zero) to U+0039 (Digit Nine)
Mostly used in the western part of the Arab world (al-maghrib al-arabi).
From U+0660 (Arabic-Indic Digit Zero) to U+0669 (Arabic-Indic Digit Nine),
Mostly used in the eastern part of the Arab world (al-mashriq al-arabi).
Hence, both sets should be supported in the user interface and both are folded to one set (Set I) at the preparation of internationalized strings (e.g., "stringprep") phase.
Connecting Multiple Words
In the Arab language words are separated by spaces. Connecting words without spaces is usually not acceptable. Therefore, a single space is the best word separator in an Arabic domain name with multiple words.
Since it is technially not visable to use space as word separator, then multiple words are separated by the character "-" dash.
