In the Unicode standard, a plane is a continuous group of 65,536 (= 216) code points. There are 17 planes, identified by the numbers 0 to 16decimal, which corresponds with the possible values 00–10hexadecimal of the first two positions in six position format (hhhhhh). The planes above plane 0 (the Basic Multilingual Plane), that is, planes 1–16, are called “supplementary planes”,[1] or humorously known as “astral planes”. As of Unicode version 7.0, six of the planes have assigned code points (characters), and four are named.

The 17 planes can accommodate 1,114,112 code points, a limit which is unlikely to be reached in the foreseeable future even if previously unknown scripts with tens of thousands of characters are discovered. The odd-looking code points limit (which is not a power of 2) is due to the design of UTF-16. In UTF-16 a "surrogate pair" of two 16-bit words is used to encode 220 code points in the planes 1 to 16, in addition to the use of single code units to encode the 216 points of plane 0.[2] This limit is not shared by UTF-8, which was designed with a limit of 231 code points (32768 planes), and can encode 221 code points (32 planes) even if limited to 4 bytes.[3] However, the Unicode Consortium has stated that the current limit will never be changed.[4][not in citation given]

Planes are further subdivided into Unicode blocks, which unlike planes, do not have a fixed size. The 252 blocks defined in Unicode 7.0 cover 23 percent of the possible code point space, and range in size from a minimum of 16 code points (eleven blocks) to a maximum of 65,536 code points (Supplementary Private Use Area-A and -B, which constitute the entirety of planes 15 and 16). For future usage, ranges of characters have been tentatively mapped out for every known current and ancient writing system.[5]

  2. ^ The total number of graphic, format and control characters (i.e., excluding private-use characters, noncharacters and surrogate code points).

Basic Multilingual Plane[edit]

A map of the Basic Multilingual Plane. Each numbered box represents 256 code points.
(As of Unicode Standard version 6.0)

The first plane, plane 0, the Basic Multilingual Plane (BMP) contains characters for almost all modern languages, and a large number of symbols. A primary objective for the BMP is to support the unification of prior character sets as well as characters for writing. Most of the assigned code points in the BMP are used to encode Chinese, Japanese, and Korean (CJK) characters.

The High Surrogates (U+D800–U+DBFF) and Low Surrogate (U+DC00–U+DFFF) codes are reserved for encoding non-BMP characters in UTF-16 by using a pair of 16-bit codes: one High Surrogate and one Low Surrogate. A single surrogate code point will never be assigned a character.

65,312 of the 65,536 code points in this plane have been allocated to a Unicode block, leaving just 224 non-allocated code points (fourteen 16-character segments).


As of Unicode 7.0, the BMP comprises the following 159 blocks:

Supplementary Multilingual Plane[edit]

A map of the Supplementary Multilingual Plane. Each numbered box represents 256 code points.
(As of Unicode Standard version 6.2)

Plane 1, the Supplementary Multilingual Plane (SMP), contains historic scripts such as Linear B, Egyptian hieroglyphs, and cuneiform scripts; historic and modern musical notation; mathematical alphanumerics; Emoji and other pictographic sets; reform orthographies like Shavian and Deseret; and game symbols for playing cards, Mah Jongg, and dominoes.

As of Unicode 7.0, the SMP comprises the following 85 blocks:

Supplementary Ideographic Plane[edit]

Plane 2, the Supplementary Ideographic Plane (SIP), is used for CJK Ideographs, mostly CJK Unified Ideographs, that were not included in earlier character encoding standards.

As of Unicode 6.1, the SIP comprises the following four blocks:

Unassigned planes[edit]

Planes 3 to 13: No characters have yet been assigned to Planes 3 through 13. Plane 3 is tentatively named the Tertiary Ideographic Plane, but as of version 7.0 there are no characters assigned to it.[6] It is reserved for Oracle Bone script, Bronze Script, Small Seal Script, additional CJK unified ideographs, and other historic ideographic scripts.[7]

It is not anticipated that all these planes will be used in the foreseeable future, given the total sizes of the known writing systems left to be encoded. The number of possible symbol characters that could arise outside of the context of writing systems is potentially huge. At the moment, these 11 planes out of 17 are unused.

Supplementary Special-purpose Plane[edit]

Plane 14 (E in hexadecimal), the Supplementary Special-purpose Plane (SSP), currently contains non-graphical characters. The first block is for deprecated language tag characters for use when language cannot be indicated through other protocols (such as the xml:lang attribute in XML). The other block contains glyph variation selectors to indicate an alternate glyph for a character that cannot be determined by context.

As of Unicode 6.1, the SSP comprises the following two blocks:

Private Use Area planes[edit]

The two planes 15 and 16, called Supplementary Private Use Area-A and -B are available for character assignment by parties outside the ISO and the Unicode Consortium. They are used by fonts internally to refer to auxiliary glyphs, for example, ligatures and building blocks for other glyphs. Such characters will have limited interoperability. Software and fonts that support Unicode will not necessarily support character assignments by other parties.

Hence plane (15 + 1)=16 is the highest plane a surrogate pair can represent. Hence 10 FFFFhex is the highest code point a surrogate pair can represent.
