Label Generation Rules for Macedonian

Overview

This document specifies a reference set of Label Generation Rules for Macedonian using a limited repertoire as appropriate for a second level domain.

Repertoire

Most references converge on 31 Cyrillic code points. There are however some discrepancies:

• Two sources (IIS) and RFC 5992 [130]) leave out U+0453 (ѓ) CYRILLIC SMALL LETTER GJE, which is clearly Macedonian, while including the similar looking U+0491 (ґ) CYRILLIC SMALL LETTER GHE WITH UPTURN which is Ukrainian. This is an obvious error.

• The same sources include U+0452 (ђ) CYRILLIC SMALL LETTER DJE mostly used in Serbian which is not included by any other sources.

Based on this, the repertoire includes U+0453 (ѓ) , but excludes U+0452 (ђ) and U+0491 (ґ) .

Because U+0450 (ѐ) CYRILLIC SMALL LETTER IE WITH GRAVE and U+045D (ѝ) CYRILLIC SMALL LETTER I WITH GRAVE were encoded later than most of the other European Cyrillic code points they are not as widely implemented and referenced but are nevertheless considered essential for Macedonian. Document [110] used for the encoding proposal in 1996 provides the evidence. There is an additional reference [605] which discusses the use of the grave accent as either a stress mark or a distinct orthographical mark.

There is a new TLD for Macedonia called .мкд administered by Macedonian Academic and Research Network (MARnet), see
http://marnet.mk/ (in Macedonian). No repertoire guidance could be found, therefore this is not used as a reference for this LGR.

Excluded code points

Letters documented in some references but not included:

• U+0452 (ђ) CYRILLIC SMALL LETTER DJE

• U+0491 (ґ) CYRILLIC SMALL LETTER GHE WITH UPTURN

Extended code points

None.

Variants

While U+0453 (ѓ) CYRILLIC SMALL LETTER GJE and U+0491 (ґ) CYRILLIC SMALL LETTER GHE WITH UPTURN have been mentioned by different references and could be perceived as variants of each other, the reference of CYRILLIC SMALL LETTER GHE WITH UPTURN appears to be in error and therefore does not justify the creation of a variant pair with CYRILLIC SMALL LETTER GJE.

Character Classes

This LGR defines no named character classes.

Rules

Common rules only:

• Hyphen Restrictions — restrictions on the allowable placement of hyphens (no leading/ending hyphen and no hyphen in positions 3 and 4). These restrictions are described in section 4.2.3.1 of RFC5891 [120]. They are implemented here as context rule on U+002D (-) (-) HYPHEN-MINUS.

• Leading Combining Marks — restrictions on the allowable placement of combining marks (no leading combining mark). This rule is described in section 4.2.3.2 of RFC5891 [120].

Actions

Actions included are the default actions for LGRs as well as those needed to invalidate labels with misplaced combining marks.

Variant-related actions included to facilitate integration as appropriate.

Methodology and Contributors

This reference LGR for Macedonian for the 2nd Level has been developed by Michel Suignard and Asmus Freytag, verified in expert reviews by Michael Everson, Nicholas Ostler, and Wil Tan, and based on multiple open public consultations.

In the listing of the repertoire by code point, references starting from [0] refer to the version of the Unicode Standard in which the corresponding code point was initially encoded. Other references, (starting from [100]) document usage of code points. For more details, see the Table of References below.

Character Classes

The following table lists all named classes with their definition and a list of their members intersected with the current repertoire (for larger classes, this list is elided).

Name	Definition	Count	Members or Ranges	Ref	Comment
implicit	Tag=sc:Cyrl	33 Elements:	{0430-0438 043A-0448 0450 0453 0455 0458-045A 045C-045D 045F}
implicit	Tag=sc:Zyyy	11 Elements:	{002D 0030-0039}

Whole label evaluation and context rules

The following table lists all named rules defined in the LGR and indicates whether they are used as trigger in an action or as context (when or not-when) for a code point. (Any use of context rules for variants is not indicated).

Name	Used as Trigger	Used as Context	Anchor	Regular Expression	Ref	Comment
leading-combining-mark	✔			(^[∅=[[∅=\p{gc=Mn}][∅=\p{gc=Mc}]]])	[120]	RFC5891 restrictions on placement of combining marks
hyphen-minus-disallowed		✔	✔	((((?<=^)⚓)|(⚓(?=$))|((?<=^..\u002D)⚓)))	[120]	RFC5891 restrictions on placement of U+002D
extended-cp				(^$)		code points from the extended range

Note: The following rules are defined but not used in this LGR: extended-cp.

Actions

The following table lists the actions that are used to assign dispositions to labels and variant labels, based on the specified conditions. The order of actions defines their precedence: the first action triggered by a label is the one defining its disposition.

#	Condition	Rule / Variant Set		Disposition	Ref	Comment
1	if label matches	leading-combining-mark	→	invalid		by default, labels with leading combining marks are invalid
2	if any label (catch-all)		→	valid		catch all (default action)
