Description

Root Zone Label Generation Rules for the Korean Script

Overview

This file contains a set of Label Generation Rules (LGR) for the Korean script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Korean Script Root Zone Label Generation Ruleset (LGR)” [Proposal-Korean], including the appendices [Proposal-Korean-Appendices]. The term “Korean script” is usually synonymous with “Hangul”. However, in the context of the Korean LGR, “Korean script” refers to the union of Hangul Syllables and Han characters used in writing Korean (Hanja). 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

The repertoire includes 11,172 Hangul syllables and 4,758 Hanja characters for a total of 15,930 code points (11,172 + 4,758). For more details, see Section 5, “Repertoire” in [Proposal-Korean].

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.

Code points outside the Korean 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

There are no variants defined between Hangul syllables. However, the LGR defines 37 variant sets among Hanja, and 7 variant sets containing at least one Hangul syllable. For more details, see Section 6 “Variants” in [Proposal-Korean].

Additional Variants:This LGR inherits additional blocked cross-script variants by integration; they may not be listed here unless they result in in-script variants. 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. For example, this LGR includes all in-script Hanja variants acquired through integration with the Chinese RZ-LGR [CLGR]. In addition to the variants listed in this LGR, integration into the Root Zone LGR will result in many additional variants to out-of-repertoire code points as result of variants defined in other LGRs, including the effects of transitivity.

Altogether, this LGR lists 289 variant sets, which can be classified as follows:

  • 283 variant sets consist of variants between two or more Hanja characters that are part of this LGR repertoire. One of these variant sets also includes a Hangul syllable.
  • 4 variant sets consist of variants between one or more in-repertoire Hanja character and a Hangul syllable. This includes one variant set already included in the previous group.
  • 3 variant sets consist of variants between one out-of-repertoire Hanja character and a Hangul syllable. One variant set also includes one in-repertoire Hanja character.

Because one variant set is classified in both group 1 and 2, the total of variant sets is 283+4+3-1 = 289.

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].

Source References for Variants

The following source references are used for variant entries in this LGR:

  • [201] – Korean-specific variants among Hanja (Table 1-1 in Appendix F)
  • [202] – Korean-specific variants between Hangul and in-repertoire Hanja (Table 1-2 in Appendix F)
  • [203] – Korean-specific variants between Hanja and out-of-repertoire Hanja (Table 1-3 in Appendix F)
  • [204] – In-repertoire Hanja variants originating from [300] (Table 2-1 in Appendix F)
  • [300] – in-repertoire variants originating from the Chinese LGR [CLGR]

Character Classes

This LGR defines the following named character classes:

  • hanja — Hanja code points
  • hangul — Hangul code points

Whole Label Evaluation (WLE) rules 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.

Korean-specific Rules and Actions

A label may consist of Hangul syllables or Hanja characters only; no mixes are allowed. See also Section 7, “Whole Label Evaluation Rules (WLE)” in [Proposal-Korean].

  • no-hangul-hanja-mixed-label — a WLE rule triggering a Korean-specific action invalidating any mixed labels

Methodology and Contributors

The Root Zone LGR for the Korean Script was developed by the Korean Generation Panel. For details on methodology and contributors, see Sections 4 and 8 in [Proposal-Korean], as well as [RZ-LGR-6-Overview].

References

References [0] to [3] refer to the Unicode Standard versions in which corresponding code points were initially encoded. For example, a reference value of [3] means a character was first encoded in Unicode Version 3.0.

References [101] and up indicate that the code point is included in one of the following source references:

  • [101] – ‘kIRG_KSource’ values starting by K0 in the Unihan database [Unihan]
  • [102] – ‘kIICore’ values including the letter ‘K’(indicating source) in the Unihan database.

Entries in the table may have multiple source reference values.

Identity mappings, where a code point is declared a variant of itself, are required by RFC 7940 and are omitted here. 661 variant records are declared in total.

Variants

Code points grouped into sets of mutual variants. Every member of a set produces the same set of variant labels, so a registration of one has implications for all the others. Sets of a single member are omitted, as are the identity mappings RFC 7940 requires each member to declare.

List
Showing the largest 10 of 289 variant sets, containing 658 variants.

Character classes

Named sets of code points that the rules below refer to.

NameDefinition
hanja {tag sc:Hani} Any Hanja code point
hangul {tag sc:Hang} Any Hangul code point

Rules

Conditions evaluated against a whole label, or against the context around a single code point. The notation borrows from regular expressions: ^ and $ anchor to the start and end of a label, . matches any code point, (?= ) and (?<= ) look ahead and behind, and * and + repeat. Two symbols are specific to rulesets: ◆ is the code point being tested, and ⟨name⟩ refers to another rule.

Actions

Actions are evaluated in the order shown. The first action whose conditions match determines the disposition of the label.

# Disposition Conditions
1 invalid label matches leading-combining-mark labels with leading combining marks are invalid MSR default
2 invalid any variant is out-of-repertoire-var any variant label with a code point out of repertoire is invalid MSR default
3 invalid label matches no-hangul-hanja-mixed-label mixed Hangul-Hanja labels are invalid
4 blocked any variant is blocked any variant label containing blocked variants is blocked MSR default
5 allocatable all variants are allocatable variant labels with all variants allocatable are allocatable MSR default
6 valid any label default catch all (default action) MSR default
