The Basic Latin or C0 Controls and Basic Latin Unicode block is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8. The block contains all the letters and control codes of the ASCII encoding.
The Basic Latin block was included in its present form from version 1.0.0 of the Unicode Standard, without addition or alteration of the character repertoire.
The C0 Controls and Basic Latin block contains six subheadings.
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.
This subheading refers to standard punctuation characters, simple mathematical operators, and symbols like the dollar sign, percent, ampersand, underscore, and pipe.
The ASCII Digits subheading contains the standard European number characters 1–9 and 0.
The Uppercase Latin alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the majuscule.
The Lowercase Latin Alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the minuscule.
The Control Character subheading contains the "Delete" character.
The Basic Latin block contains twelve emoji: U+0023, U+002A and U+0030–U+0039. 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.
All of these base characters default to a text presentation.
