Description

Root Zone Label Generation Rules for the Gujarati Script

Overview

This file contains a set of Label Generation Rules (LGR) for the Gujarati script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Gujarati Script Label Generation Ruleset for the Root Zone” [Proposal-Gujarati]. 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 Section 5, “Repertoire” in [Proposal-Gujarati], the Gujarati LGR contains 65 single code points. This repertoire covers multiple languages written using the Gujarati script and ranging from 1 to 4 on the [EGIDS] scale.

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 and one or more other character categories. For each repertoire element, one or more references document sufficient justification for inclusion in the repertoire; see the “References” below.

Variants

According to Section 6, “Variants”, in [Proposal-Gujarati], there are no characters or character sequences in the Gujarati repertoire that look exactly alike. Hence no variants have been defined.

However, Gujarati has some cases of confusingly similar combinations which have been listed in Appendix A in [Proposal-Gujarati].

Character Classes

Gujarati is an alphasyllabary and the heart of the writing system is the akshar. This is the unit which is instinctively recognized by users of the script. The writing system of Gujarati could be summed up as composed of Consonants, the Implicit Vowel Killer: Halant, Vowels, Anusvara, Candrabindu, Nukta, Visarga and Avagraha.

Consonants: Gujarati consonants contain an implicit vowel schwa /ə/. The traditional classification categorizes them according to their phonetic properties. There are 5 varga groups (classes) and one non-varga group. Each varga, which corresponds to a particular stop, contains five consonants classified as per their properties. The first four consonants are classified on the basis of Voicing and Aspiration and the last is the corresponding nasal. More details in Section 3.4.1, “The Consonants” of the [Proposal-Gujarati].

Halant: All consonants contain the implicit vowel (schwa). A special sign is needed to denote that this implicit vowel is stripped off. This is known as the Halant, U+0ACD. The Halant thus joins two consonants and creates conjuncts, which generally combine 2 to 4 consonants. In rare cases the Halant can join up to 5 consonants. More details in Section 3.4.2, “The Implicit Vowel Killer: Halant” in [Proposal-Gujarati].

Vowels and Matras: Separate symbols exist for all vowels, which are either pronounced independently at the beginning or attached to a consonant. To indicate the latter (other than the implicit one), a Vowel modifier (matra) is attached to the consonant. Since the consonant has a built-in schwa, there are equivalent matras for all vowels excepting U+0A85. More details in Section 3.4.3, “Vowels” in [Proposal-Gujarati].

Anusvara: In Gujarati, the Anusvara U+0A82 has a dual function. On the one hand, it acts as homorganic nasal, that is, it replaces a conjunct group of a Nasal Consonant+Halant+Consonant belonging to that particular varga. On the other hand, before a non-varga consonant the Anusvara represents a nasal sound. Gujarati and its dialects prefer the Anusvara to the corresponding half-nasal. More details in Section 3.4.4, “The Anusvara” in [Proposal-Gujarati].

Nukta: Traditionally Gujarati does not admit the Nukta. Gujarati grammarians in their inventory of the Gujarati alphabet do not admit this diacritic. However, the Nukta is used to represent content where Perso-Arabic characters have to be transliterated. It follows specific consonants listed in set C1. More details in Section 3.4.6, “Nukta” in [Proposal-Gujarati].

Visarga and Avagraha: The Visarga U+0A83 is frequently used in Sanskrit and represents a sound very close to /h/, as in દુઃખ /du:kh/ sorrow, unhappiness. It is used sparingly in Gujarati with a few words borrowed from Sanskrit. The Avagraha is rarely used and excluded from the LGR. More details in Section 3.4.7, “Visarga and Avagraha” in [Proposal-Gujarati].

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 default prohibition on leading combining marks is equivalent to ensuring that a label only starts with a consonant or vowel. The actions compute a label disposition based on WLE rules or variant mapping types.

Gujarati-specific Rules

These rules have been drafted to ensure that the prospective Gujarati label conforms to akshar formation norms as desired in Gujarati script. These norms are exclusively presented as context rules.

The following symbols are used in the WLE rules:
C → Consonant
M → Matra
V → Vowel
B → Anusvara
X → Visarga
H → Halant/Virama
N → Nukta
C1 → Consonants used with Nukta

The rules are:

  • 1. N: must be preceded by any of the specific set of Consonants (C1)
  • 2. H: must be preceded either by C or N
  • 3. X: must be preceded by any of V, C, N or M
  • 4. B: must be preceded by any of V, C, N or M
  • 5. M: must be preceded either by C or N

More details in Section 7, “Whole Label Evaluation Rules (WLE)” in [Proposal-Gujarati].

Methodology and Contributors

The Root Zone LGR for the Gujarati Script was developed by the Neo-Brahmi Generation Panel (NBGP), the members of which have experience in linguistics and computational linguistics in a wide variety of languages written with Neo-Brahmi scripts. Under the Neo-Brahmi Generation Panel, there are nine scripts belonging to separate Unicode blocks. Each of these scripts has been assigned a separate LGR, with the Neo-Brahmi GP ensuring that the fundamental philosophy behind building each LGR is in sync with all other Brahmi-derived scripts. For further details on methodology and contributors, see Sections 4 and 8 in [Proposal-Gujarati], as well as [RZ-LGR-6-Overview].

Character classes

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

NameDefinition
C {tag Consonant} Any Gujarati consonant
V {tag Vowel} Any Gujarati vowel letter
M {tag Matra} Any Gujarati vowel sign
N {tag Nukta} The Gujarati Nukta
C1 {tag C1} Consonants used with Gujarati Nukta

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.
