<p>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.</p>
<p>Where the <i>type</i> of both forward and reverse mappings are the same, a single value is given in the Type(s) column, otherwise the types for forward and reverse mappings, as well as comments and references are listed above one another.</p>
<p>A mapping where source and target are the same is <i>reflexive</i>. 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 “≡”.</p>
<p>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.</p>

For more details on this proposal see "Proposal for a Tamil Script Root Zone Label Generation Rule-Set (LGR)" [Proposal].The format of this file follows [RFC 7940].</p><h2>Repertoire</h2><p>According to Section 5, "Repertoire" in [Proposal] the Tamil LGR contains 48 unique code points and 4 sequences.</p><p>The repertoire is based on [MSR-4], which is a subset of Unicode 6.3 [Unicode 6.3].</p><h2>Variants</h2><p>According to Section 6 "Variants", in "[Proposal]", this LGR defines four sequences as variants. Two of them are variants to single code points; the other two are variants of each other. </p><p>Variant Disposition: all defined variants look exactly alike and can cause confusion even to a careful observer; except as noted variants have been assigned "blocked" type.There is no preference among these variants. Whichever label containing either of these variants is chosen earlier, blocks the other equivalent variant label. The variant Shri described in section 6.1.3 is a case of variant where exactly same visual form is rendered with two distinct sequences. Also, in the minds of the user, regardless of which sequence they choose to input, both are intended to be the same akshar i.e. Shri. Hence, it is imperative that both the sequences be treated as same in terms of Variant analysis and any label formed with either form should be made available to the same entity. This variant pair is thus being proposed as an Allocatable variant. (For more details see Section 6.1 of [Proposal].)</p><p>In addition to these, this LGR defines 6 cross-script variants with the Malayalam script. </p><h2>Character Classes</h2><p>Tamil is an alphasyllabary and the heart of the writing system isthe Akshar. It is this unit, which is instinctively recognized by users of the script.The writing system of Tamil could be summed up as composed of Consonants,the Implicit Vowel Killer: Halant, Vowels and Visarga/Aytham.</p><p>Consonants: More details in Section "3.3.1The Consonants" of the [Proposal].</p><p>Virama2/Pulli: All consonants contain an implicit vowel (a) within them. A specialsign is needed to denote that this implicit vowel is stripped off. This is knownas the virama "்" (U+0BCD). The virama thus joins two adajcent consonants. In Tamil, thereare only two cases where this forms conjuncts. More details in Section "3.3.2 Virama2/Pulli" ofthe [Proposal].</p><p>Vowels: Separate symbols exist for all Vowels that are pronounced independentlyeither at the beginning or after another vowel sound. To indicate a Vowel sound other thanthe implicit one following a consonant, a Vowel sign (Matra) is attached to the consonant.Since the consonant has a built in ‘a’, there are equivalent Matras for all vowels excepting the அ.More details in Section "3.3.3 Vowels" of the [Proposal].</p><p>Visarga/Ayutham: The Visarga is also used in Tamil and represents a sound very close to /ḵ/.More details in Section "3.3.4 Visarga/Aytham" of the [Proposal].</p><h2>Whole Label Evaluaton (WLE) rules</h2><h3>Default Whole Label Evaluation Rules</h3><p>The LGR includes the set of required default WLE rules and actions applicable tothe Root Zone and defined in [MSR-4]. They are marked with ⍟.</p><h3>Tamil specific Rules</h3><p>These rules have been drafted to ensure that the prospective Tamil label conformsto akshar formation norms as desired in Tamil script. These norms are exclusivelypresented as context rules. </p><p>Following symbols used in the WLE rules:<br/>C → Consonant<br/>M → Matra<br/>H → Virama/Pulli<br/>X → TAMIL SIGN VISARGA = Aytham</p><p>The rules are: </p><ol><li>H: must be preceded by C</li><li>M: must be preceded by C</li><li>X: cannot be preceded by X</li><li>Two representations of 'Shri' cannot be mixed in a label</li></ol><p>More details in Section 7 "Whole Label Evaluation Rules (WLE)" of the [Proposal] </p><h2>Overall Development Process and Methodology</h2><p>Under the Neo-Brahmi Generation Panel, there are many different scriptsbelonging to separate Unicode blocks. Each of these scripts will be assigneda separate LGR; however Neo-Brahmi GP did ensure that the fundamental philosophybehind building those LGRs are all in sync with all other Brahmi derivedscripts. This is the Tamil LGR, which caters to the Tamil language writtenusing Tamil script.</p><h2>References</h2><p>Following references are cited in this document:</p><dl class="references"><dt>[MSR-4]</dt><dd>Integration Panel, "Maximal Starting Repertoire — MSR-4 Overview and Rationale",7 February 2019, https://www.icann.org/en/system/files/files/msr-4-overview-25jan19-en.pdf</dd><dt>[Proposal]</dt><dd>Neo-Brahmi Generation Panel, "Proposal for a Tamil Script Root Zone Label Generation Rule-Set (LGR)", 20 February 2019, https://www.icann.org/en/system/files/files/proposal-tamil-lgr-20feb19-en.pdf</dd><dt>[RFC 7940]</dt><dd>Davies, K. and A.
