Subheadings

The C0 Controls and Basic Latin block contains six subheadings.^[5]

C0 controls

The C0 Controls, referred to as C0 ASCII control codes in version 1.0, are inherited from ASCII and other 7-bit and 8-bit encoding schemes. The Alias names for C0 controls are taken from the ISO/IEC 6429:1992 standard.^[5]

ASCII punctuation and symbols

This subheading refers to standard punctuation characters, simple mathematical operators, and symbols like the dollar sign, percent, ampersand, underscore, and pipe.^[5]

ASCII digits

The ASCII Digits subheading contains the standard European number characters 1–9 and 0.^[5]

Uppercase Latin alphabet

The Uppercase Latin alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the majuscule.^[5]

Lowercase Latin alphabet

The Lowercase Latin Alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the minuscule.^[5]

Control character

The Control Character subheading contains the "Delete" character.^[5]

Notes 1.^ As of Unicode version 9.0

Emoji

The Basic Latin block contains twelve emoji: U+0023, U+002A and U+0030–U+0039.^[6][7] They're keycap base characters, for example #️⃣ (U+0023 NUMBER SIGN U+FE0F VS16 U+20E3 COMBINING ENCLOSING KEYCAP).

A standardized variant is defined for a zero with a short diagonal stroke: U+0030 DIGIT ZERO, U+FE00 VS1 (0︀).

The block has 24 standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the following twelve base characters: U+0023, U+002A and U+0030–U+0039.^[8]

All of these base characters default to a text presentation.
