This document specifies a reference set of Label Generation Rules for Georgian Mkhedruli (modern) for the second level domain or domains identified above. The starting point for the development of this LGR can be found in the related Root Zone LGR [RZ-LGR-Geor]. The format of this file follows [RFC 7940]. This LGR is adapted from the “Reference LGR for the Second Level for the Georgian Mkhreduli” [Ref-LGR-und-Geor], for details, see Change History below.
For details and additional background on the Georgian script, see “Proposal for a Georgian Script Root Zone LGR” [Proposal-Georgian].
The repertoire contains 33 code points for letters used by languages that are actively written in the Mkhedruli alphabet. The repertoire is a subset of [Unicode 11.0.0]. For details, see Section 5, “Repertoire” in [Proposal-Georgian]. (The proposal cited has been adopted for the Georgian script portion of the Root Zone LGR.)
For the second level, the repertoire has been augmented with the ASCII digits, U+0030 to U+0039, plus U+002D HYPHEN-MINUS, for a total of 44 repertoire elements.
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. For code points in the repertoire, comments identify the language using the code point.
The variants defined in this LGR are limited to those required for use in zones not shared with any other script. As such, this LGR does not define cross-script variants. However, using this LGR concurrently with any LGR for Myanmar in the same zone will create potential cross-script issues. For details, see Section 6, “Variants” in [Proposal-Georgian]. Mitigation of these cross-script variants can be addressed by using the Common LGR. For details, see Section 3, “Use of Multiple Reference LGRs in the Same Zone” in [Level-2-Overview]. In addition to variants defined by this LGR, the full variant information related to this script and required for concurrent use with the Myanmar LGR(s) can be found in the following LGR: [Ref-LGR-Myanmar-Full-Variant-Script]
This version of the LGR defines no variants. For details, see Section 6, “Variants” in [Proposal-Georgian].
Additional variants When integrated to be used with another script LGR in the same zone, this LGR may inherit additional blocked cross-script variants by integration; they may not be listed here unless they reflect resulting in-script variants. Always use an applicable merged, or Common LGR created by integration for determining cross-script collisions of labels.
The specification of variants in this LGR follows the guidelines in [RFC 8228].
This LGR does not define named character classes.
By default, the LGR includes the rules and actions to implement the following restrictions mandated by the IDNA protocol. They are marked with ⍟.
This LGR includes the default actions for LGRs as well as the action needed to invalidate labels with misplaced combining marks. They are marked with ⍟. For a description see [RFC 7940].
This LGR does not define rules specific to the Georgian script.
The LGR in this document has been adapted from the corresponding Reference LGR for the Second Level. The Second Level Reference LGR for the Georgian Mkhreduli was developed by Michel Suignard and Asmus Freytag, based on the Root Zone LGR for the Georgian script and information contained or referenced therein; see [RZ-LGR-Geor]. Suitable extensions for the second level have been applied according to the [Guidelines] and with community input. The original proposal for a Root Zone LGR for the Georgian script, that this LGR is based on, was developed by the Georgian Generation Panel. For more information on methodology and contributors to the underlying Root Zone LGR, see Sections 4 and 8 in [Proposal-Georgian], as well as [RZ-LGR-Overview].
Unicode Version has been updated.
Adopted from the Second Level Reference LGR for the Georgian Mkhreduli [Ref-LGR-und-Geor] without normative changes.

Reference [0] refers to the Unicode Standard version in which corresponding code points were initially encoded. Reference [100] corresponds to a source given in [Proposal-Georgian] for justifying the inclusion of for the corresponding code points. Entries in the table may have multiple source reference values.
