= Code point
A <code point> is a numerical position in a coded character space. <Unicode> defines <code points> from `U+0000` through `U+10FFFF`; some are assigned to characters, while others have reserved, private-use, surrogate or noncharacter roles. A <Unicode scalar value> excludes surrogate <code points>.<The Unicode Standard Version 17 Core Specification>[Chapter3, definitionsD9–D12 andD76]{ref}
A <code point> is distinct from an encoded <byte> and from a displayed <grapheme cluster>. For example, `U+00E9` encodes as two <bytes> in <UTF-8>. The visible accented letter can also be represented by `U+0065 U+0301`, two <code points> that may form one <grapheme cluster>. A <code unit> is a unit of an encoding form, such as one <byte> in <UTF-8>. Counting these units answers different questions from counting user-perceived characters.
