Summary

• the Basic Multilingual Plane (BMP - Plane 0) (version bmp-4-18, 2006-04-27)
• the Supplementary Multilingual Plane (SMP - Plane 1) (version smp-4-17, 2006-04-27)
• the Supplementary Ideographic Plane (SIP - Plane 2) (version sip-4-4, 2006-04-27), and
• the Supplementary Special-purpose Plane (SSP - Plane 14) (version ssp-4-2, 2005-06-27)

Presentation conventions

• 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 Standard uses a single-column presentation. The multi-column presentation is available only for the BMP and only in the published ISO/IEC 10646 standard and its amendments, available for purchase from ISO or from 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 a document containing exploratory material.
• Unallocated:
  Three question marks - ??? - in a block indicates that no suggestion has been made regarding allocation to the column(s).

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 (number of columns) with regard to the allocation proposed.

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