A map of the Supplementary Multilingual Plane. Each numbered box represents 256 code points.
A map of the Supplementary Ideographic Plane. Each numbered box represents 256 code points.

In the Unicode standard, a plane is a continuous group of 65,536 (= 2) 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”, or humorously known as “astral planes”. As of Unicode version 8.0, six of the planes have assigned code points (characters), and four are named.
