This document specifies a reference set of Label Generation Rules for Georgian Mkhedruli (modern) for the second level. The starting point for the development of this LGR can be found in the related Root Zone LGR [RZ-LGR-3-Geor]. For details and additional background on the script, see "Proposal for a Georgian Script Root Zone LGR [Proposal-Georgian]". The format of this file follows [RFC 7940].
This is a DRAFT document released for public comments and not final. Please see the announcement on the ICANN website for public comments on the Second Level Reference LGRs for details on how to submit comments.
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 6.3]. 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 (0) to U+0039 (9), and U+002D (-) HYPHEN-MINUS for a total of 44 repertoire elements.
Each code point or range is tagged with the script or scripts that the code point is used with, and one or more references documenting sufficient justification for inclusion in the repertoire, see "References" below.
According to Section 6, "Variants" in [Proposal-Georgian], this LGR defines no variants.
This LGR does not define character classes.
Actions include the default actions for LGRs as well as that needed to invalidate labels with misplaced combining marks. They are marked with ⍟. For a description see [RFC 7940].
According to Section 7, "Whole Label Evaluation (WLE) Rules" in [Proposal-Georgian], this LGR does not define rules specific to Georgian.
This reference LGR for Georgian Mkhedruli for the 2nd Level has been developed by Michel Suignard and Asmus Freytag, based on the Root Zone LGR for Georgian Mkhedruli and information contained or referenced therein, see [RZ-LGR-3-Geor]. Suitable extensions for the second level have been applied according to the [Guidelines]. The original proposal for a Root Zone LGR for Georgian Mkhedruli, 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].

For references consulted particularly in designing the repertoire for the Georgian script for the second level. please see details in the Table of References below. 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.
