Summary

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

the Basic Multilingual Plane (BMP - Plane 0) (version bmp-4-8, 2004-06-24)
the Supplementary Multilingual Plane (SMP - Plane 1) (version smp-4-7, 2004-07-03)
the Supplementary Ideographic Plane (SIP - Plane 2) (version sip-4-1, 2003-05-16), and
the Supplementary Special-purpose Plane (SSP - Plane 14) (version ssp-4-1, 2003-07-15)

are included in this document.

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

See History of Changes for changes from the previous version of this snapshot.

Presentation conventions

Conventions that are common to all the roadmap tables presented in this document are given below. Any additional conventions specific to a particular table are detailed after the heading for that table.

Published:
Bold text indicates an allocated (that is, published) character collection. There is a link to the corresponding chart on the Unicode web site. Note: For the CJK Unified ideographs in the BMP, the Unicode standards uses a single-column presentation. The multi-column presentation is available only in the published ISO/IEC 10646 standard and its amendments, available for purchase from ISO or various national standards organizations.
Accepted for inclusion:
(Bold text between parentheses) indicates scripts which have been formally accepted by UTC or WG 2 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 WG 2. 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 UTC or to 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.

Roadmap to the SMP

The following table comprises a proportional map of Plane 1, the SMP (Supplementary Multilingual Plane).

The SMP is tentatively mapped out to the following zones (some of these zones are shown shaded in the table):

00010000-000100FF Linear B
00010100-000101FF Ancient numeric systems
00010200-000102FF unassigned
00010300-000107FF Alphabetic and syllabic LTR scripts
00010800-00010FFF Alphabetic and syllabic RTL scripts (shaded)
00011000-000117FF Brahmic scripts
00011800-00011FFF African and other syllabic scripts (shaded)
00012000-00012FFF Cuneiform and other ancient scripts
00013000-00013FFF Scripts for invented languages (shaded)
00014000-00016BFF Egyptian and Mayan hieroglyphs
00016C00 00016FFF Aztec pictograms (shaded)
00017000-0001B5FF Large Asian scripts
0001B600-0001CFFF unassigned (shaded)

Roadmap to the SIP

The following table comprises a proportional map of Plane 2, the SIP (Supplementary Ideographic Plane).

Plane 2 is tentatively mapped out to the following zones:

00020000-0002A6DF CJK Unified Ideographs Extension B
0002A6E0-0002F7FF unassigned
0002F800-0002FA1F CJK Compatibility Ideographs Supplement
0002FA20-0002FFFD unassigned

NOTE: Should Plane 2 prove insufficient for future Han character encoding, it is anticipated that further allocations may be provided on Plane 3.

Several of the proposals have been accepted by UTC prior to WG2 M44 - their status in this document is marked as - under consideration - " (Text between parentheses)" instead of - accepted for inclusion - " (Bold text between parentheses)". Their status may change after WG2 meeting M44. See pipeline.html for a list of these characters or scripts.
