Unicode Symbol
In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but is nonetheless available for use as part of a text. Many of the symbols are drawn from existing character sets or ISO/ IEC or other national and international standards. The Unicode Standard states that "The universe of symbols is rich and open-ended," but that in order to be considered, a symbol must have a "demonstrated need or strong desire to exchange in plain text." This makes the issue of what symbols to encode and how symbols should be encoded more complicated than the issues surrounding writing systems. Unicode focuses on symbols that make sense in a one-dimensional plain-text context. For example, the typical two-dimensional arrangement of electronic diagram symbols justifies their exclusion. (Legacy characters such as box-drawing characters, Symbols for Legacy Computing and the Symbols for Legacy Computing Supplement, are an exception, since these sym ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. ...

Letterlike Symbols
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." Symbols Glyph variants Variation selectors may be used to specify chancery (U+FE00) vs roundhand (U+FE01) forms, if the font supports them: The remainder of the set is at Mathematical Alphanumeric Symbols. Block Emoji The Letterlike Symbols block contains two emoji An emoji ( ; plural emoji or emojis; , ) is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages.

Mathematical Alphanumeric Symbols
Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin alphabet, Latin and Greek alphabet, Greek letters and decimal numerical digit, digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics. By providing uniformity over numerous mathematical articles and books, these conventions help to read mathematical formulas. These also may be used to differentiate between concepts that share a letter in a single problem. Unicode now includes many such symbols (in the range U+1D400–U+1D7FF). The rationale behind this is that it enables design and usage of special mathematical characters (typeface, fonts) that include all necessary properties to differentiate from other alphanumerics, e.g. in mathematics an italic type, italic letter "𝐴" can have a different meaning from a roman type, roman letter "A".

Dingbats (Unicode Block)
Dingbats is a Unicode block containing dingbats (or typographical ornaments, like the ❦ FLORAL HEART character). 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 (called variant selectors). The block, originally named "Zapf Dingbats", was added to the Unicode Standard in October 1991, with the release of version 1.0. The block name was changed from "Zapf Dingbats" to "Dingbats" in June 1993, with the release of 1.1. Chart Emoji The Dingbats block contains 33 emoji. 66 standardized variants are defined to specify emoji-style (like ) or text presentation (like ) for 33 characters. Em ...

Enclosed Ideographic Supplement
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. Block Emoji The Enclosed Ideographic Supplement block contains fifteen emoji: U+1F201–U+1F202, U+1F21A, U+1F22F, U+1F232–U+1F23A and U+1F250–U+1F251.

Enclosed Alphanumerics
Enclosed Alphanumerics is a Unicode block of Typography, typographical symbols of an alphanumeric within a circle, a bracket or other not-closed enclosure, or ending in a full stop. It is currently fully allocated. Within the Basic Multilingual Plane, a few additional enclosed numerals are in the Dingbat#Unicode, Dingbats and the Enclosed CJK Letters and Months blocks. There is also a block with more of these characters in the Supplementary Multilingual Plane named Enclosed Alphanumeric Supplement (U+1F100–U+1F1FF), as of Unicode 6.0. Purpose Many of these characters were originally intended for use as bullets for lists.''The Unicode Standard'', 6.0.1 The parenthesized forms are historically based on typewriter approximations of the circled versions. Although these roles have been supplanted by styles and other markup in "rich text" contexts, the characters are included in the Unicode standard "for interoperability with the legacy East Asian character sets and for t ...

Enclosed Alphanumeric Supplement
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. The block is mostly an extension of the Enclosed Alphanumerics block, containing further enclosed alphanumeric characters which are not included in that block or Enclosed CJK Letters and Months. Most of the characters are single alphanumerics in boxes or circles, or with trailing commas. Two of the symbols are identified as dingbats. A number of multiple-letter enclosed abbreviations are also included, mostly to provide compatibility with Broadcast Markup Language standards (see ARIB STD B24 character set) and Japanese telecommunications networks' emoji sets. The block also includes the regional indicator symbols to be used for emoji country flag support. Block Emoji The Enclosed Alphanumeric Supplement ...
