Code point
no link
     i18n:
Code point. A code point value represents the position of a character in 
a coded character set. For example, the code point for the letter á in 
the Unicode coded character set is 225 in decimal, or 0xE1 in 
hexadecimal notation. Hexadecimal notation is commonly used for 
referring to code points. See also Unicode code point 
<https://w3c.github.io/i18n-glossary/#dfn-unicode-code-point>.
    INFRA:
A code pointis a Unicode code point and is represented as "U+" followed 
by four-to-six ASCII upper hex digits 
<https://infra.spec.whatwg.org/#ascii-upper-hex-digit>, in the range 
U+0000 to U+10FFFF, inclusive. A code point 
<https://infra.spec.whatwg.org/#code-point>’s valueis its underlying 
number.

A code point <https://infra.spec.whatwg.org/#code-point> may be followed 
by its name, by its rendered form between parentheses when it is not 
U+0028 or U+0029, or by both. Documents using the Infra Standard are 
encouraged to follow code points 
<https://infra.spec.whatwg.org/#code-point> by their name when they 
cannot be rendered or are U+0028 or U+0029; otherwise, follow them by 
their rendered form between parentheses, for legibility.

A code point <https://infra.spec.whatwg.org/#code-point>’s name is 
defined in Unicode and represented in ASCII uppercase 
<https://infra.spec.whatwg.org/#ascii-uppercase>. [UNICODE]

Code unit.
     no link
i18n:
Code unit. The units of data used by a character encoding 
<https://w3c.github.io/i18n-glossary/#dfn-character-encoding> to encode 
or serialize characters into a programming language or other serialized 
form (such as a file). Common code units are 8-, 16-, and 32-bits in 
size. On the Web we are mostly concerned with /bytes/, which are 
technically "8-bit code units". However, in Javascript a |char| is a 
16-bit code unit (related to the UTF-16 encoding of Unicode)
     INFRA:
A stringis a sequence of unsigned 16-bit integers, also known as code 
units. A string <https://infra.spec.whatwg.org/#string> is also known as 
a JavaScript string <https://infra.spec.whatwg.org/#string>. Strings 
<https://infra.spec.whatwg.org/#string> are denoted by double quotes and 
monospace font.

*//*/Scalar value/, see Unicode scalar value 
<https://w3c.github.io/i18n-glossary/#dfn-scalar-value>.

INFRA:

A scalar valueis a code point 
<https://infra.spec.whatwg.org/#code-point> that is not a surrogate 
<https://infra.spec.whatwg.org/#surrogate>.


Surrogate code point
     link
i18n:

Surrogate code point. Unicode definition 
<https://www.unicode.org/glossary/#surrogate_code_point>: "A Unicode 
code point in the range U+D800..U+DFFF. Reserved for use by UTF-16, 
where a pair of surrogate code units (a high surrogate followed by a low 
surrogate) “stand in” for a supplementary code point 
<https://w3c.github.io/i18n-glossary/#dfn-supplementary-code-point>." 
This term is also defined by [INFRA 
<https://w3c.github.io/i18n-glossary/#bib-infra>].

     INFRA:

A surrogateis a leading surrogate 
<https://infra.spec.whatwg.org/#leading-surrogate> or a trailing 
surrogate <https://infra.spec.whatwg.org/#trailing-surrogate>.
