Unicode Planes

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 16, which corresponds with the possible values 00–10₁₆ of the first two positions in six position hexadecimal format (U+''hhhhhh''). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version , five of the planes have assigned code points (characters), and seven are named.

The limit of 17 planes is due to UTF-16, which can encode 2²⁰ code points (16 planes) as pairs of words, plus the BMP as a single word. UTF-8 was designed with a much larger limit of 2³¹ (2,147,483,648) code points (32,768 planes), and would still be able to encode 2²¹ (2,097,152) code points (32 planes) even under the current limit of 4 bytes.

The 17 planes can accommodate 1,114,112 code points. Of these, 2,048 are Universal Character Set characters#Surrogates, surrogates (used to make the pairs in UTF-16), 66 are Universal Character Set characters#Non-characters, non-characters, and 137,468 are Universal Character Set characters#Private-Use Characters, reserved for private use, leaving 974,530 for public assignment.

Planes are further subdivided into Unicode blocks, which, unlike planes, do not have a fixed size. The 327 blocks defined in Unicode cover 26% of the possible code point space, and range in size from a minimum of 16 code points (sixteen 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 most known current and ancient writing systems.

Overview

Assigned characters

Basic Multilingual Plane

The first plane, plane 0, the Basic Multilingual Plane (BMP) contains characters for almost all modern languages, and a large number of Unicode symbols, 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, CJK) characters.

The High Surrogate (U+D800–U+DBFF) and Low Surrogate (U+DC00–U+DFFF) codes are reserved for UTF-16#Code points from U+010000 to U+10FFFF, 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.

65,520 of the 65,536 code points in this plane have been allocated to a Unicode block, leaving just 16 code points in a single unallocated range (2FE0..2FEF).

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.

, the SIP comprises the following six blocks:
* CJK Unified Ideographs Extension B (20000–2A6DF)
* CJK Unified Ideographs Extension C (2A700–2B73F)
* CJK Unified Ideographs Extension D (2B740–2B81F)
* CJK Unified Ideographs Extension E (2B820–2CEAF)
* CJK Unified Ideographs Extension F (2CEB0–2EBEF)
* CJK Compatibility Ideographs Supplement (2F800–2FA1F)

Tertiary Ideographic Plane

Plane 3 is the Tertiary Ideographic Plane (TIP). CJK Unified Ideographs Extension G was added to the TIP in Unicode 13.0, released in March 2020. It also is tentatively allocated for Oracle bone script, Oracle Bone script and Small Seal Script.

, the TIP comprises the following two blocks:
* CJK Unified Ideographs Extension G (30000–3134F)
* CJK Unified Ideographs Extension H (31350–323AF)

Unassigned planes

Planes 4 to 13 (planes to in hexadecimal): No characters have yet been assigned, or proposed for assignment, to Planes 4 through 13.

Supplementary Special-purpose Plane

Plane 14 ( in hexadecimal) is designated as the Supplementary Special-purpose Plane (SSP). It comprises the following two Unicode block, blocks, :
*Tags (Unicode block), Tags (E0000–E007F)
*Variation Selectors Supplement (Unicode block), Variation Selectors Supplement (E0100–E01EF) – used to indicate alternate glyphs for characters.

Private Use Area Planes

The two planes 15 and 16 (planes and in hexadecimal) each contain a "Private Use Areas, Private Use Area". They contain blocks named Supplementary Private Use Area-A (PUA-A) and -B (PUA-B). The Private Use Areas are available for use by parties outside ISO and Unicode (private character encoding).
