Description

Root Zone Label Generation Rules for the Armenian Script

Overview

This file contains a set of Label Generation Rules (LGR) for the Armenian script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for an Armenian Script Root Zone LGR” [Proposal-Armenian]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-6]. The format of this file follows [RFC 7940].

Repertoire

According to [Proposal-Armenian], the range of permissible code points is U+0561 ա–U+0586 ֆ and supports the Armenian language as written in the Armenian script.

Note that U+0587 և is not included in the repertoire because it is DISALLOWED in IDNA2008 [RFC 5892] and therefore not permissible in IDNs.

The repertoire is contained in [MSR-6], which is a subset of [Unicode 16.0.0].

As part of the Root Zone, this LGR includes neither decimal digits nor the HYPHEN-MINUS.

Repertoire Listing: Each code point or range is tagged with the script or scripts with which the code point is used. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see the “References” below. For code points that are part of the repertoire, comments identify the language using the code point.

Code points outside the Armenian script repertoire that are listed in this file are targets for out-of-repertoire variants and are identified by a reflexive (identity) variant of type “out-of-repertoire-var”. They do not form part of the repertoire.

Variants

According to Section 6, “Variants” in [Proposal-Armenian], there are no variants defined within the Armenian script. However, integration with the Latin and Greek LGRs does introduce some in-script variants due to cross-script variant transitivity.

In particular, the Armenian LGR inherits the following in-script variant as result of integration:

  • Blocked: U+0572 ղ — U+0578 ո.

Additional Cross-script Variants

Where homoglyphs or near homoglyphs exist between the Latin, Greek, Cyrillic and Armenian scripts, out-of-repertoire variants are defined with a comment “Cross-script homoglyph” or “Cross-script near homoglyph” respectively. As result of integration, including the effects of cross-script transitivity, the number of cross-script variants listed for these scripts may be larger than defined in Section 6, “Variants” in [Proposal-Armenian]. These are generally not marked.

This LGR inherits additional blocked cross-script variants by integration; they may not be listed here unless they result in in-script variants. However, for consistency, the variant mappings among the closely related scripts Armenian, Cyrillic, Greek and Latin are listed in full. See the merged, Common LGR [RZ-LGR-6] for details of all applicable cross-script variants, including any not listed here; always use the Common LGR for determining cross-script collisions of labels.

Variant Disposition: All variants are of type “blocked”, making labels that differ only by these variants mutually exclusive: whichever label containing either of these variants is chosen earlier would be delegated, while any other equivalent labels should be blocked. There is no preference among these labels.

This LGR does not define allocatable variants.

The specification of variants in the Root Zone LGR follows the guidelines in [RFC 8228].

Character Classes

The LGR does not define character classes.

Whole Label Evaluation (WLE) and Context Rules

Default Whole Label Evaluation Rules and Actions

The LGR includes the set of required default WLE rules and actions applicable to the Root Zone and defined in [MSR-6]. They are marked with ⍟. The actions compute a label disposition based on WLE rules or variant mapping types.

Armenian-specific Rules

This LGR does not define rules specific to Armenian.

Methodology and Contributors

The Root Zone LGR for the Armenian Script was developed by the Armenian Generation Panel. For details on methodology and contributors, see Sections 4 and 8 in [Proposal-Armenian], as well as [RZ-LGR-6-Overview]. After initial review by the Integration Panel, this LGR was deferred until it could be considered in the context of all related scripts. The LGR has subsequently been updated to reflect inherited variants resulting from integration.

Repertoire by Code Point

The following table lists the repertoire by code point (or code point sequence). The data in the Script and Name column are extracted from the Unicode character database. Where a comment in the original LGR is equal to the character name, it has been suppressed.

For any code point or sequence for which a variant is defined, additional information is provided in the Variants column. Some code points or sequences listed in the following table are not part of the repertoire itself; they document targets for out-of-repertoire variant mappings as indicated. See also the legend provided below the table.

Legend

Code Point
A code point or code point sequence.
Glyph
The shape displayed depends on the fonts available to your browser.
Script
Shows the script property value from the Unicode Character Database. Combining marks may have the value Inherited and code points used with more than one script may have the value Common.
Name
Shows the character or sequence name from the Unicode Character Database.
Ref
Links to the references associated with the code point or sequence, if any.
Variants
Link to the variant set the code point or sequence is a member of, except where a coded point or sequence maps only to itself, in which case the type of that mapping is listed.
Comment
The comment as given in the XML file. However, if the comment for this row consists only of the code point or sequence name, it is suppressed in this view. By convention, comments starting with “=” denote an alias. If present, the symbol ⍟ marks a default item shared among a set of LGRs.
✔ - core repertoire
A check mark in the Part-of-repertoire column indicates a code point is part of the core repertoire.
✗ - out-of-repertoire
A code point shown with is not part of the repertoire. It is listed only because it is the target of an out-of-repertoire-var variant mapping.

Variant Sets

The following tables list all variant sets defined in this LGR, except for singleton sets. Each table lists all variant mapping pairs of the set; one per row. Mappings are assumed to be symmetric: each row documents both forward (→) and reverse (←) mapping directions. In each table, the mappings are sorted by Source value in ascending code point order; shading is used to group mappings from the same source code point or sequence.

Where the type of both forward and reverse mappings are the same, a single value is given in the Type column; otherwise the types for forward and reverse mappings, as well as comments and references, are listed above one another. For summary counts, both forward and reverse mappings are always counted separately.

A mapping where source and target are the same is reflexive. Variant sets consisting of only a single reflexive mapping are not shown as a set. Instead, the variant type of the mapping is listed in the Variants column of the Repertoire by Code Point table. Reflexive mappings that are part of a larger set are indicated with a “≡” and are counted once per entry.

In any LGR with variant specifications that are well behaved, all members within each variant set are defined as variants of each other; the mappings in each set are symmetric and transitive; and all variant sets are disjoint.

Common Legend

Source
By convention, the smaller of the two code points in a variant mapping pair.
Target
By convention, the larger of the two code points in a variant mapping pair.
Glyph
The shape displayed for source or target depends on the fonts available to your browser.
→ - forward
Indicates that Type, Ref and Comment apply to the mapping from source to target.
← - reverse
Indicates that Type, Ref and Comment apply to the reverse mapping from target to source.
↔ - both
Indicates that Type, Ref and Comment apply to both forward and reverse mapping.
- reflexive
Indicates that Type, Ref and Comment are for a reflexive mapping where source equals target.
Type
The type of the variant mapping, including predefined variant types such as “allocatable” and “blocked”; or any that are defined specifically for this LGR. A reflexive variant type “out-of-repertoire-var” designates the target as not part of the repertoire; it is required as target for one or more variant mappings that cross repertoire boundaries. In this LGR, types for variant mappings between out-of-repertoire code points are shown in italic while types for pure in-repertoire variant mappings are shown in bold.
Ref
One or more reference IDs (optional). A “/” separates references for reverse / forward mappings, if different.
Comment
A descriptive comment (optional). A “/” separates comments for reverse / forward mappings, if different.
