Description
Root Zone Label Generation Rules for the Telugu Script
Overview
This file contains Label Generation Rules (LGR) for the Telugu script for the Root Zone. For more details on this LGR and additional background on the script, see “Proposal for a Telugu Script Root Zone Label Generation Ruleset (LGR)” [Proposal-Telugu]. This file is one of a set of LGR files that together form an integrated LGR for the DNS Root Zone [RZ-LGR-5]. The format of this file follows [RFC 7940].
Repertoire
According to Section 5, “Repertoire” in [Proposal-Telugu], the Telugu LGR contains 63 single code points. This LGR primarily caters to the Telugu language written using the Telugu script. Several other languages with [EGIDS] level above 4 were also considered in the analysis.
The repertoire is based on [MSR-5], which is a subset of [Unicode 11.0].

As part of the Root Zone, this LGR includes neither decimal digits nor the HYPHEN-MINUS.
Code points outside the Telugu script that are listed in this file are targets for out-of-script variants and are identified by a reflexive (identity) variant of type “out-of-repertoire-var”. They do not form part of the repertoire.
Each code point is tagged with the script or scripts with which the code point is used, one or more other character categories, and one or more references documenting sufficient justification for inclusion in the repertoire; see “References” below. Comments provide alternate names of some code points.
Variants
According to Section 6, “Variants”, in [Proposal-Telugu], this LGR defines cross-script variants which are “Confusing due to deviation from normally perceived character formations by larger linguistic community”. These cases are not of mere visual similarity; they can cause confusion even to a careful observer and hence have been defined as variants. There are no in-script variants defined for Telugu.
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 any other equivalent label should be blocked. There is no preference among these variants.
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 Telugu orthography superficially resembles a series of circles and semi-circles. Most consonants carry a tick mark called ‘talakattu’. The writing system is classified as abugida type or alphasyllabary. The alphabet consists of vowels, consonants and modifiers. Each of these vowels and consonants has one or more secondary allographs.
Consonants: The Telugu consonants contain an implicit vowel /a/. More details in Section 3.5.4, “The Consonants” in [Proposal-Telugu].
Vowels and dependent vowel signs: There are fourteen vowel characters in the common inventory of which one is rarely used: U+0C0C. It and the two obsolete vowels, U+0C60 and U+0C61, are excluded from this LGR. Each vowel, except U+0C05 has a dependent vowel sign, modifying the vowel of the consonant they follow. These signs may have different appearance depending on the size and shape of the consonant that functions as an anchor. More details in Section 3.5.1, “The vowels and vowel modifiers” in [Proposal-Telugu].
Anusvara or sunna: The Anusvara or sunna represents a homorganic nasal before the corresponding consonant and as a substitute to transcribe word final /mu/. Essentially, it substitutes a cluster of a Nasal Consonant+Halant before a consonant. More details in Section 3.5.2, “The Anusvara or sunna” in [Proposal-Telugu].
Visarga: Visarga denotes the glottal check.
Halant: A special sign is needed whenever the implicit vowel in the preceding consonant is stripped off. This symbol is known as the Halant. (Any vowel sign will also override the implicit vowel). More details in Section 3.5.1, “The vowels and vowel modifiers” in [Proposal-Telugu].
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-5]. 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.
Telugu-specific Rules
These rules have been formulated so that they can be adopted for LGR specification.
The following symbols are used in the WLE rules:
C → Consonant
M → Matra (Dependent vowel signs)
V → Vowel
B → Anusvara (Bindu)
X → Visarga
H → Halant / Virama
The rules are:
- 1. H: must be preceded by C
- 2. M: must be preceded by C
- 3. X: must be preceded by V, M or C
- 4. B: must be preceded by V, M or C
- 6. V: cannot be preceded by H
More details in Section 7, “Whole Label Evaluation Rules (WLE)” in [Proposal-Telugu]. The numbering of the rules given here, follows that document.
Methodology and Contributors
The Root Zone LGR for the Telugu 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-Telugu], as well as [RZ-LGR-5-Overview].

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
Character classes
Named sets of code points that the rules below refer to.
| Name | Definition |
|---|---|
C |
{tag Consonant}
Any Telugu consonant
|
V |
{tag Vowel}
Any Telugu independent vowel
|
M |
{tag Matra}
Any Telugu vowel sign (matra)
|
H |
{tag Halant}
The Telugu Halant / Virama
|
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.
