Overview#Code Point or code position is any of the numerical values that make up the code space.
Many Code Point represent single characters but they can also have other meanings, such as for formatting.
For example, the character encoding scheme
- ASCII comprises 128 code points in the range 0hex to 7Fhex
- Extended ASCII comprises 256 code points in the range 0hex to FFhex, and Unicode comprises 1,114,112 code points in the range 0hex to 10FFFFhex.
- Unicode code space is divided into seventeen planes (the basic multilingual plane, and 16 supplementary planes), each with 65,536 (= 216) code points. Thus the total size of the Unicode code space is 17 × 65,536 = 1,114,112.
