#
#Apart from the general rules defined in IDNA2008 CORE Internet Council of Registrars implements some further rules. These will be described in the following sections.
#
#For every registered Arabic script IDN, an index (or canonical) string will be computed and stored in the SRS database. The index string 
#is produced by applying the rules from the section below to the IDN U-label. If no rule applies or if all applying rules map their respective character to itself, then the index 
#string will be the same as the registered string. Once an Arabic script IDN is registered, other domain names that map to the same index string will be unavailable for 
#registration. Additionally, there are some rules that specifically prohibit a certain combination of Arabic characters within a domain label. Such labels will also be 
#unavailable for registration.
#
#The table presented here is in compliance with the ICANN Guidelines for the Implementation of 
#Internationalized Domain Names Version 3.0 and is intended for publication in the 
#IANA Repository of TLD IDN Practices, for the information of prospective holders of domains 
#in .sport and for the users of resources within those domains.

#
#1.1 Table of Allowed Characters and their Joining Property

#The table below lists the characters allowed in the Unicode representation of IDNs associated with the Arabic script. The second column shows the character property used in the 
#rules below. Columns are delimited by semicolons. The "#" symbol denotes start of a comment that continues to the end of line.

#1.2 Pattern Syntax
#
#The following rules will have a pattern describing a character from the above table to be matched. Since the Arabic characters cannot be considered on a one-by-one basis, a 
#look-behind and look-ahead pattern is (optionally) added to each rule. A rule applies to a domain label if the given pattern matches a character within the label and the #characters before and after match the patterns given in look-behind and look-ahead, respectively. The terms 'before' and 'after' are considered to be in relation to the on-the-#wire order of the characters.
#
#The following character properties will be used in the patterns.

#* {L} denotes characters that are left-joining
#* {R} denotes characters that are right-joining
#* {D} denotes characters that are dual-joining (i.e. both left- and right-joining)
#* {U} denotes characters that are unable to join
#* {T} denotes combining characters
#* {1} denotes the ASCII digits Zero - Nine (i.e., 0030..0039)
#* {2} denotes the Arabic digits Zero - Nine (i.e., 0660..0669)
#* {3} denotes the extended Arabic digits Zero - Nine (i.e., 06F0..06F9)
#* {} denotes the empty word (no character)
#* character classes can be combined, e.g. {LD} denotes characters that are either left-joining or dual-joining
#
#Apart from the character properties necessary for the Arabic characters, the used pattern syntax is defined by the following syntax elements which are based on the regular #expression syntax.
#
#* . denotes any character
#* ^ denotes the beginning of the label
#* $ denotes the end of the label
#* | denotes an alternative
#* (...) groups a subpattern
#* an asterisk (*) denotes any number of occurrences, including zero
#* ZWNJ denotes the zero width non-joiner character (U+200C)
#* U+XXXX denotes the Unicode character with the hexadecimal code point XXXX
#
#
#1.3 Rules Describing Invalid Labels
#
#If any of the following rules is matched, the respective domain label is rejected and may not be registered. Note that some special cases of the rules below are already included 
#in IDNA2008. Excluding those special cases would only have made the rules more complicated and less intuitive so they were kept.
#
#Comment:      prevent confusion that may arise in conjunction with certain fonts
#Look-behind:   
#Pattern:      U+0637 | U+0638 | U+06BE
#Look-ahead:   ZWNJ {T}* {RD}
#Action:       reject
#
#Comment:      a label may not start with a digit
#Look-behind:  ^ 
#Pattern:      {123} 
#Look-ahead:
#Action:       reject
#
#Comment:      consecutive hyphens are not allowed in a label
#Look-behind:  U+002D
#Pattern:      U+002D
#Look-ahead:
#Action:       reject
#
#Comment:      no mixing of the three digit sets is allowed (part 1)
#Look-behind:  {23} .*
#Pattern:      {1}
#Look-ahead:
#Action:       reject
#
#Comment:      no mixing of the three digit sets is allowed (part 2)
#Look-behind:  {13} .*
#Pattern:      {2}
#Look-ahead:
#Action:       reject
#
#Comment:      no mixing of the three digit sets is allowed (part 3)
#Look-behind:  {12} .*
#Pattern:      {3}
#Look-ahead:
#Action:       reject
#
#
#1.4 Rules for Variant and Index Generation
#
#If any of the following rules matches, the character from the pattern will have an index character. This index character is used to determine the index string for the whole 
#label (simply by replacing each character by its index character). Furthermore, labels with at least one matching rule will have label variants. The variants are determined by #replacing the character by any one of the allowed variants.
#
#Note that for every variant, the previous rules to determine invalid labels also have to be checked to make sure a variant is a valid domain label.
#
#
#1.4.1 ZWNJ IDNA2003 workaround
#
#The rule is due to the fact that several browsers still do not support IDNA2008 in respect of the ZWNJ character. By implementing the older version IDNA2003 they simply remove 
#any ZWNJ occurrence. The following rule removes every ZWNJ from a domain name and thus makes two domains that only differ in the appearance of ZWNJ characters variants of each #other.
