Plane 0: Basic Multilingual Plane

Introduction

Plane 0: Basic Multilingual Plane

Plane 1: Supplementary Multilingual Plane

Plane 2: Secondary Ideographic Plane

Plane 3: Tertiary Ideographic Plane

Plane 14: Supplementary Special-purpose Plane

Summary

The following table shows a map of the actual and proposed allocation on Plane 0, the BMP (Basic Multilingual Plane). A description of the presentation conventions used in the table is at the bottom of this page.

Presentation conventions

Text on Blue indicates a published character collection. Text on Violet indicates a published character collection with predominant right-to-left directionality. For blocks containing assigned graphic or format characters, there is a link to the charts on the Unicode web site.
(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.
(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.
¿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.
Color highlighting is used to indicate blocks and unassigned ranges which default to right-to-left character behavior.
Grey shading is used to indicate ranges of control characters and noncharacters.

NOTE: When scripts are actually proposed to the UTC or to WG2, 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.

The Script Encoding Working Group maintains and updates this document as a service to the Unicode Technical Committee and to ISO/IEC JTC1/SC2/WG2.
