Bref aperçu :

Afin d’améliorer la transparence et l’uniformité du processus de révision de la table des noms de domaine internationalisés (IDN) et de faciliter ainsi les opérations de registre de nouveaux gTLD, l’ICANN a mis au point des tables d’IDN de référence supplémentaires dans un format pouvant être lu par un ordinateur, appelées règles de génération d'étiquettes (LGR) de référence pour le second niveau. Les tables d’IDN de référence se fondent sur les Directives pour l’élaboration des règles de génération d'étiquettes (LGR) de référence, qui ont été finalisées après examen de la communauté. Ces LGR de référence seront utilisées pour la révision des tables d’IDN soumises par les registres gTLD, par exemple dans le cadre de la politique d’évaluation des services de registre (RSEP).

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
