In The Unicode Standard, Georgian script implementation is discussed in  Chapter 7 Europe-I.

The Georgian script (Mkhedruli and Khutsuri) was encoded in The Unicode Standard version 1.0. Since that time the encoding has undergone a number of modifications; the script is now encoded in the following blocks:

BlocksCharacter RangeAdded in Unicode VersionUnicode chart

Georgian Supplement 2D00..2D2F 4.1  U2D00.pdf

Subsequent to version 1.1, the following characters have been added to the Georgian script:
