The Basic Latin Unicode block, [3] sometimes informally called C0 Controls and Basic Latin, [4] 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. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character.
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. [5] Its block name in Unicode 1.0 was ASCII. [6]
The C0 Controls and Basic Latin block contains six subheadings. [8]
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. [8]
This subheading refers to standard punctuation characters, simple mathematical operators, and symbols like the dollar sign, percent, ampersand, underscore, and pipe. [8]
The ASCII Digits subheading contains the standard European number characters 1–9 and 0. [8]
The Uppercase Latin alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the majuscule. [8]
The Lowercase Latin Alphabet subheading contains the standard 26-letter unaccented Latin alphabet in the minuscule. [8]
The Control Character subheading contains the "Delete" character. [8]
The table below shows the number of letters, symbols and control codes in each of the subheadings in the C0 Controls and Basic Latin block.
| Subheading | Number of symbols | Range of characters |
|---|---|---|
| C0 controls | 32 control codes | U+0000 to U+001F |
| ASCII punctuation and symbols | 33 punctuation marks and symbols | U+0020 to U+002F, U+003A to U+0040, U+005B to U+0060 and U+007B to U+007E |
| ASCII digits | 10 digits | U+0030 to U+0039 |
| Uppercase Latin Alphabet | 26 unaccented Latin letters in the majuscule. | U+0041 to U+005A |
| Lowercase Latin Alphabet | 26 unaccented Latin letters in the minuscule. | U+0061 to U+007A |
| Control character | 1 control code containing the "Delete" character. | U+007F |

Several of the characters are defined to render as a standardized variant if followed by variant indicators.
A variant is defined for a zero with a short diagonal stroke: U+0030 DIGIT ZERO, U+FE00 VS1 (0︀). [9] [10]
Twelve characters (#, *, and the digits) can be followed by U+FE0E VS15 or U+FE0F VS16 to create emoji variants. [11] [12] [13] [14] They are keycap base characters, for example #️⃣ (U+0023 NUMBER SIGN U+FE0F VS16 U+20E3 COMBINING ENCLOSING KEYCAP). The VS15 version is "text presentation" while the VS16 version is "emoji-style". [10]

Miscellaneous Symbols is a Unicode block (U+2600–U+26FF) containing glyphs representing concepts from a variety of categories: astrological, astronomical, chess, dice, musical notation, political symbols, recycling, religious symbols, trigrams, warning signs, and weather, among others.
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.
Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike."
Miscellaneous Technical is a Unicode block ranging from U+2300 to U+23FF. It contains various common symbols which are related to and used in the various technical, programming language, and academic professions. For example:
Supplemental Arrows-B is a Unicode block containing miscellaneous arrows, arrow tails, crossing arrows used in knot descriptions, curved arrows, and harpoons.
Miscellaneous Symbols and Arrows is a Unicode block containing arrows and geometric shapes with various fills, astrological symbols, technical symbols, intonation marks, and others.
The Latin-1 Supplement is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). C1 Controls (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.
The ISO basic Latin alphabet is an international standard for a Latin-script alphabet that consists of two sets of 26 letters, codified in various national and international standards and used widely in international communication. They are the same letters that comprise the current English alphabet. Since medieval times, they are also the same letters of the modern Latin alphabet. The order is also important for sorting words into alphabetical order.
Enclosed Alphanumerics is a Unicode block of typographical symbols of an alphanumeric within a circle, a bracket or other not-closed enclosure, or ending in a full stop.
KS X 1001, "Code for Information Interchange ", formerly called KS C 5601, is a South Korean coded character set standard to represent Hangul and Hanja characters on a computer.
CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages. It also contains one Chinese character.
Enclosed Alphanumeric Supplement is a Unicode block consisting of Latin alphabet characters and Arabic numerals enclosed in circles, ovals or boxes, used for a variety of purposes. It is encoded in the range U+1F100–U+1F1FF in the Supplementary Multilingual Plane.
Miscellaneous Symbols and Pictographs is a Unicode block containing meteorological and astronomical symbols, emoji characters largely for compatibility with Japanese telephone carriers' implementations of Shift JIS, and characters originally from the Wingdings and Webdings fonts found in Microsoft Windows.
Enclosed CJK Letters and Months is a Unicode block containing circled and parenthesized Katakana, Hangul, and CJK ideographs. Also included in the block are miscellaneous glyphs that would more likely fit in CJK Compatibility or Enclosed Alphanumerics: a few unit abbreviations, circled numbers from 21 to 50, and circled multiples of 10 from 10 to 80 enclosed in black squares.
Mahjong Tiles is a Unicode block containing characters depicting the standard set of tiles used in the game of Mahjong.
Dingbats is a Unicode block containing dingbats. Most of its characters were taken from Zapf Dingbats; it was the Unicode block to have imported characters from a specific typeface; Unicode later adopted a policy that excluded symbols with "no demonstrated need or strong desire to exchange in plain text", and thus no further dingbat typefaces were encoded until Webdings and Wingdings were encoded in Version 7.0. Some ornaments are also an emoji, having optional presentation variants.
Enclosed Ideographic Supplement is a Unicode block containing forms of characters and words from Chinese, Japanese and Korean enclosed within or stylised as squares, brackets, or circles. It contains three such characters containing one or more kana, and many containing CJK ideographs. Many of its characters were added for compatibility with the Japanese ARIB STD-B24 standard. Six symbols from Chinese folk religion were added in Unicode version 10.
Halfwidth and Fullwidth Forms is the name of a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode. It is the second-to-last block of the Basic Multilingual Plane, followed only by the short Specials block at U+FFF0–FFFF. Its block name in Unicode 1.0 was Halfwidth and Fullwidth Variants.
Transport and Map Symbols is a Unicode block containing transportation and map icons, largely for compatibility with Japanese telephone carriers' emoji implementations of Shift JIS, and to encode characters in the Wingdings and Wingdings 2 character sets.
Variation Selectors is a Unicode block containing 16 variation selectors used to specify a glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1–VS4, VS7, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively.
