Summary

This document is the latest snapshot of the roadmap documents that has been presented to and adopted by WG2 (ISO/IEC JTC1/SC2/WG 2). Four tables containing the roadmaps to

the Basic Multilingual Plane (BMP - Plane 0) (versionbmp-3-10, 2002-12-03)
the Supplementary Multilingual Plane (SMP - Plane 1) (version smp-3-4, 2002-12-03)
the Supplementary Ideographic Plane (SIP - Plane 2) (version sip-3-1, 2002-11-11), and
the Supplementary Special-purpose Plane (SSP - Plane 14) (version ssp-3-1, 2002-01-22)

are included in this document.

The Roadmap ad hoc group maintains and updates this document as a service to the UTC (Unicode Technical Committee) and to WG2 (ISO/IEC JTC1/SC2/WG2). The latest working version of this document can be found at http://www.unicode.org/roadmaps. This document is informative. Please send corrigenda and other comments to the authors.

Presentation conventions

Conventions common to all the roadmap tables that appear later in this document are given below. Additional conventions specific to a particular table are to be found after the heading for that table.

Published:
Bold text indicates an allocated (that is, published) character collection. There is a link to the charts on the Unicode web site.
Accepted for inclusion:
(Bold text between parentheses) indicates scripts which have been formally accepted by UTC or WG2 for processing toward inclusion in the standard. There is generally a link to a mature proposal for the script.
Under consideration:
(Text between parentheses) indicates scripts for which proposals have been formally submitted to the UTC or to WG2. There is generally a link to the formal proposal.
Exploratory:
¿Text between question marks? indicates scripts for which detailed proposals have not yet been written. There may be a link to an exploratory code table.
Open:
??? in a block indicates that no suggestion has been made regarding the block allocation.

NOTE: When scripts are actually proposed to the UTC (Unicode Technical Committee) or to ISO/IEC SC 2/WG 2, the practice is to "front" them in the zones to which they are tentatively allocated, and to adjust the block size with regard to the allocation proposed.

The size and location of the unallocated script blocks are merely proposals based on the current state of planning. The size and location of a script may change during final allocation of the script.

NOTE: As far as is possible, half-row (128) and surrogate block (4096) boundaries are observed in planning. This means that scripts do not cross these boundaries where possible.

Roadmap to the BMP

The following table comprises a proportional map of Plane 0, the BMP (Basic Multilingual Plane).

Areas containing RTL (right to left) scripts, as well as the Surrogates Zone (S-Zone of 10646) and the Private Use Area are shaded grey here informatively.
