Dear Team members I have been asked by Microsoft Arabia
to review the internet draft entitled “Internationalized Domain Names in
Applications, Revised (IDNABIS)” from the site http://www.ietf.org/dyn/wg/charter/idnabis-charter.html.
These drafts include: The Unicode code points and IDNA I have found that there were tremendous efforts behind the
work that will lead soon to the use of Domain names in different languages. I have gone through all available documents in the site. I
needed also to revisit previous versions of the Internet-Drafts. However, as my
specialization is in Arabic Computing, I have concentrated my study on the
document “Right-to-left
scripts for IDNA “. I have reviewed the disallowed code points of Arabic which are
listed below. A nice thing I have noticed that most of characters that may
cause misleading or confusion have been disallowed as it is stated in The Unicode code
points and IDNA .
The new algorithmic model used in IDNA2008 allows the label when the final character in a right to left string requires a combining mark in order to be correctly represented. It allows diacritics to be included as they are of type NSM (None spacing Marks). It seems this is important in some right to left languages such as Yiddish and Dhivehi. However, allowing Arabic diacritics marks (064b – 065E), which are parts of the non spacing marks, in domain names will be problematic in the future and might cause a lot of confusion in domain names. The question could be simplified as to do want a label in a domain name such as وردة to be different from a label such as وَردة? The question in different words that if we allow diacritics on the domain name then a domain name like مايكروسوفت.شركةWill be different than theمَايكروسوفت.شركةBecause in the second one there is a diacritic on the first letter.Although this diacritic is implicit in the first one. So this might cause a lot of problems in the domain names registration and owner claims.Moreover, for the displaying order of the labels of a domain name I have tried the following hypothetical domain names:Husni.حاسب.شركة حسني.حاسب.شركة husni.حاسب.com حسني.computer.شركة حسني.حاسب.com husni.computer.شركة husni.computer.com The following is an image of the network order from right to left for Arabic of the above: It is clear that when we use two consecutive RTL labels separated by dots and followed by one LTR label the display order does not look as it should. The same is true that when we use two consecutive LTR labels separated by dots and followed by one RTL. The question is should we allow such confusion?As I have introduced earlier, it an excellent effort towards the internationalization of domain names.Thank you and best wishes Husni Al-Muhtasebhttp://faculty.kfupm.edu.sa/ics/muhtaseb/ From: Mamdouh Najjar
