Unicode: Code points

In running text, an individual code point is expressed as U+xxxx where xxxx is the four to six hexadecimal digits long hex-value of the code point, for example U+0051.

A range of code points is expresses as U+xxxx-U+yyyy or U+xxxx..U+yyyy.

The U+ portion can sometimes be omitted for brevity, but is required in rule NR2 for cases where characters have names algorithmically derived from their code points.

Some programming languages use \uxxxx to embed a Code point into a string literal. For example, in Python:

>>> print('\u0052\u0065\u006e\u00e9')

In PowerShell, the code point number for a character can be determined like so:

PS:>  [int][char] 'a'
97
PS:>  [int][char] 'λ'
955

Perl function ord

The VBA function chrW(u) converts the Unicode codepoint u into a character.

The Excel worksheet function unicode()

White space code points

A HTML entity allows to specify a code point in a HTML document.
