The Universal Coded Character Set, most commonly called the <a href="/wiki/Universal_Character_Set" class="mw-redirect" title="Universal Character Set">Universal Character Set</a> (<abbr title="abbreviated">abbr.</abbr> UCS, official designation: <a href="/wiki/International_Organization_for_Standardization" title="International Organization for Standardization">ISO</a>/<a href="/wiki/International_Electrotechnical_Commission" title="International Electrotechnical Commission">IEC</a> 10646), is an international standard to map <a href="/wiki/Character_(computing)" title="Character (computing)">characters</a>, discrete symbols used in <a href="/wiki/Orthography" title="Orthography">natural language</a>, <a href="/wiki/Mathematical_notation" title="Mathematical notation">mathematics</a>, <a href="/wiki/Musical_notation" title="Musical notation">music</a>, and other domains, to unique <a href="/wiki/Machine-readable_data" class="mw-redirect" title="Machine-readable data">machine-readable data</a> values. By creating this mapping, the UCS enables computer <a href="/wiki/Software_company" title="Software company">software vendors</a> to <a href="/wiki/Interoperate" class="mw-redirect" title="Interoperate">interoperate</a>, and transmit—<a href="https://en.wiktionary.org/wiki/interchange" class="extiw" title="wikt:interchange">interchange</a>—<a href="/wiki/Character_encoding#Unicode_encoding_model" title="Character encoding">UCS-encoded</a> text <a href="/wiki/String_(computer_science)" title="String (computer science)">strings</a> from one to another. Because it is a <i>universal</i> map, it can be used to represent multiple languages at the same time. This avoids the confusion of using multiple legacy <a href="/wiki/Character_encodings" class="mw-redirect" title="Character encodings">character encodings</a>, which can result in the same sequence of codes having multiple interpretations depending on the character encoding in use, resulting in <i><a href="/wiki/Mojibake" title="Mojibake">mojibake</a></i> if the wrong one is chosen. </p><p>UCS has a potential capacity of over 1 million characters. Each UCS character is abstractly represented by a <a href="/wiki/Code_point" title="Code point">code point</a>, an integer between 0 and 1,114,111 (1,114,112 = 2<sup>20</sup> + 2<sup>16</sup> <i>or</i> 17 × 2<sup>16</sup> = <style data-mw-deduplicate="TemplateStyles:r886049734">.mw-parser-output .monospaced{font-family:monospace,monospace}</style><span class="monospaced"><a href="/wiki/Hexadecimal" title="Hexadecimal">0x</a>110000</span> <a href="/wiki/Code_points" class="mw-redirect" title="Code points">code points</a>), used to represent each character within the internal logic of <a href="/wiki/Text_processing" title="Text processing">text processing</a> software.

Often, the terms <i>character</i> and <i>code point</i> will be used interchangeably. However, when a distinction is made, a <i>code point</i> refers to the <a href="/wiki/Integer" title="Integer">integer</a> of the character: what one might think of as its address.

Each block is a grouping of characters by their use such as "mathematical operators" or "Hebrew script characters". When assigning characters to previously unassigned code points, the Consortium typically allocates entire blocks of similar characters: for example all the characters belonging to the same script or all similarly purposed symbols get assigned to a single block.

The general categories are: letter, mark, number, punctuation, symbol, or control (in other words a formatting or non-graphical character). </p><p>Types include: </p> <ul><li><b>Modern, Historic, and Ancient Scripts</b>. As of 2024 (Unicode 16.0), the UCS identifies 168 scripts that are, or have been, used throughout of the world. Many more are in various approval stages for future inclusion of the UCS.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup></li> <li><b>International Phonetic Alphabet</b>. The UCS devotes several blocks (over 300 characters) to characters for the <a href="/wiki/International_Phonetic_Alphabet" title="International Phonetic Alphabet">International Phonetic Alphabet</a>.</li> <li><b>Combining Diacritical Marks</b>. An important advance conceived by Unicode in designing the UCS and related algorithms for handling text was the introduction of combining diacritic marks. By providing accents that can combine with any letter character, the Unicode and the UCS reduce significantly the number of characters needed. While the UCS also includes precomposed characters, these were included primarily to facilitate support within UCS for non-Unicode text processing systems.</li> <li><b>Punctuation</b>. Along with unifying diacritical marks, the UCS also sought to unify punctuation across scripts. Many scripts also contain punctuation, however, when that punctuation has no similar semantics in other scripts.</li> <li><b>Symbols</b>. Many mathematics, technical, geometrical and other symbols are included within the UCS. This provides distinct symbols with their own code point or character rather than relying on switching fonts to provide symbolic glyphs. <ul><li><b>Currency</b>.</li> <li><b>Letterlike</b>. These symbols appear like combinations of many common Latin scripts letters such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">℅</span>. Unicode designates many of the letterlike symbols as compatibility characters usually because they can be in plain text by substituting glyphs for a composing sequence of characters: for example substituting the glyph <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">℅</span> for the composed sequence of characters <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">c/o</span>.</li> <li><b>Number Forms</b>. Number forms primarily consist of precomposed fractions and Roman numerals. Like other areas of composing sequences of characters, the Unicode approach prefers the flexibility of composing fractions by combining characters together. In this case to create fractions, one combines numbers with the fraction slash character (U+2044). As an example of the flexibility this approach provides, there are nineteen precomposed fraction characters included within the UCS. However, there are an infinity of possible fractions. By using composing characters the infinity of fractions is handled by 11 characters (0-9 and the fraction slash). No character set could include code points for every precomposed fraction. Ideally a text system should present the same glyphs for a fraction whether it is one of the precomposed fractions (such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">⅓</span>) or a composing sequence of characters (such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">1⁄3</span>). However, web browsers are not typically that sophisticated with Unicode and text handling. Doing so ensures that precomposed fractions and combining sequence fractions will appear compatible next to each other.</li> <li><b>Arrows</b>.</li> <li><b>Mathematical</b>.</li> <li><b>Geometric Shapes</b>.</li> <li><b>Legacy Computing</b>.</li> <li><b>Control Pictures</b> Graphical representations of many control characters.</li> <li><b>Box Drawing</b>.</li> <li><b>Block Elements</b>.</li> <li><b>Braille Patterns</b>.</li> <li><b>Optical Character Recognition</b>.</li> <li><b>Technical</b>.</li> <li><b>Dingbats</b>.</li> <li><b>Miscellaneous Symbols</b>.</li> <li><b>Emoticons</b>.</li> <li><b>Symbols and Pictographs</b>.</li> <li><b>Alchemical Symbols</b>.</li> <li><b>Game Pieces</b> (chess, checkers, go, dice, dominoes, mahjong, playing cards, and many others).</li> <li><b>Chess Symbols</b></li> <li><b><a href="/wiki/Tai_Xuan_Jing" class="mw-redirect" title="Tai Xuan Jing">Tai Xuan Jing</a></b>.</li> <li><b>Yijing Hexagram Symbols</b>.</li></ul></li> <li><b>CJK</b>. Devoted to ideographs and other characters to support languages in China, Japan, Korea (CJK), Taiwan, Vietnam, and Thailand. <ul><li><b>Radicals and Strokes</b>.</li> <li><b>Ideographs</b>. By far the largest portion of the UCS is devoted to ideographs used in languages of Eastern Asia. While the glyph representation of these ideographs have diverged in the languages that use them, the UCS unifies these <a href="/wiki/Han_characters" class="mw-redirect" title="Han characters">Han characters</a> in what Unicode refers to as Unihan (for Unified Han). With Unihan, the text layout software must work together with the available fonts and these Unicode characters to produce the appropriate glyph for the appropriate language. Despite unifying these characters, the UCS still includes over 97,000 Unihan ideographs.</li></ul></li> <li><b>Musical Notation</b>.</li> <li><b>Duployan shorthands</b>.</li> <li><b>Sutton SignWriting</b>.</li> <li><b>Compatibility Characters</b>. Several blocks in the UCS are devoted almost entirely to compatibility characters. Compatibility characters are those included for support of legacy text handling systems that do not make a distinction between character and glyph the way Unicode does. For example, many Arabic letters are represented by a different glyph when the letter appears at the end of a word than when the letter appears at the beginning of a word. Unicode's approach prefers to have these letters mapped to the same character for ease of internal machine text processing and storage. To complement this approach, the text software must select different glyph variants for display of the character based on its context. Over 4000 characters are included for such compatibility reasons.</li> <li><b>Control Characters</b>.</li> <li><b>Surrogates</b>. The UCS includes 2048 code points in the Basic Multilingual Plane (BMP) for surrogate code point pairs. Together these surrogates allow any code point in the sixteen other planes to be addressed by using two surrogate code points. This provides a simple built-in method for encoding the 20.1 bit UCS within a 16 bit encoding such as UTF-16. In this way UTF-16 can represent any character within the BMP with a single 16-bit word. Characters outside the BMP are then encoded using two 16-bit words (4 octets or bytes total) using the surrogate pairs.</li> <li><b>Private Use</b>. The consortium provides several private use blocks and planes that can be assigned characters within various communities, as well as operating system and font vendors.</li> <li><b>Noncharacters</b>. The consortium guarantees certain code points will never be assigned a character and calls these noncharacter code points. These include the range U+FDD0..U+FDEF, and the last two code points of each plane (ending in the hexadecimal digits FFFE and FFFF).<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup></li></ul> <div class="mw-heading mw-heading2"><h2 id="Special-purpose_characters">Special-purpose characters</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Universal_Character_Set_characters&action=edit&section=5" title="Edit section: Special-purpose characters"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/Unicode_control_characters" title="Unicode control characters">Unicode control characters</a></div> <p>Unicode codifies over a hundred thousand characters.

In the same situation a more complex engine may combine information from the font with its own rules to achieve its own idea of best rendering. To implement all recommendations of the Unicode specification, a text engine must be prepared to work with fonts of any level of sophistication, since contextual substitution and positioning rules do not exist in some font formats and are optional in the rest. The <a href="#Fraction_slash">fraction slash</a> is an example: complex fonts may or may not supply positioning rules in the presence of the fraction slash character to create a fraction, while fonts in simple formats cannot. </p> <div class="mw-heading mw-heading3"><h3 id="Byte_order_mark">Byte order mark</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Universal_Character_Set_characters&action=edit&section=6" title="Edit section: Byte order mark"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>When appearing at the head of a text file or stream, the <a href="/wiki/Byte_order_mark" title="Byte order mark">byte order mark</a> (BOM) U+FEFF hints at the encoding form and its byte order. </p><p>If the stream's first byte is 0xFE and the second 0xFF, then the stream's text is not likely to be encoded in <a href="/wiki/UTF-8" title="UTF-8">UTF-8</a>, since those bytes are invalid in UTF-8.

Such a fraction should be displayed as a unit, such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">¾</span>. If the displaying software is incapable of mapping the fraction to a unit, then it can also be displayed as a simple linear sequence as a fallback (for example, 3/4). If the fraction is to be separated from a previous number, then a space can be used, choosing the appropriate width (normal, thin, zero width, and so on). For example, 1 + <small>ZERO WIDTH SPACE</small> + 3 + <small>FRACTION SLASH</small> + 4 is displayed as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">1¾</span>.</p></blockquote> <p>By following this Unicode recommendation, text processing systems yield sophisticated symbols from plain text alone. Here the presence of the fraction slash character instructs the layout engine to synthesize a fraction from all consecutive digits preceding and following the slash. In practice, results vary because of the complicated interplay between fonts and layout engines. Simple text layout engines tend not to synthesize fractions at all, and instead draw the glyphs as a linear sequence as described in the Unicode fallback scheme. </p><p>More sophisticated layout engines face two practical choices: they can follow Unicode's recommendation, or they can rely on the font's own instructions for synthesizing fractions. By ignoring the font's instructions, the layout engine can guarantee Unicode's recommended behavior. By following the font's instructions, the layout engine can achieve better <a href="/wiki/Typography" title="Typography">typography</a> because placement and shaping of the digits will be tuned to that particular font at that particular size. </p><p>The problem with following the font's instructions is that the simpler font formats have no way to specify fraction synthesis behavior. Meanwhile, the more complex formats do not require the font to specify fraction synthesis behavior and therefore many do not. Most fonts of complex formats can instruct the layout engine to replace a plain text sequence such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">1⁄2</span> with the precomposed <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">½</span> glyph. But because many of them will not issue instructions to synthesize fractions, a plain text string such as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">221⁄225</span> may well render as <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">22½25</span> (with the <span class="nounderlines" style="border: 1px solid var(--border-color-muted,#ddd); color: var(--color-base); background-color: var( --background-color-neutral-subtle, #fdfdfd); padding: 1px 1px;">½</span> being the substituted precomposed fraction, rather than synthesized). In the face of problems like this, those who wish to rely on the recommended Unicode behavior should choose fonts known to synthesize fractions or text layout software known to produce Unicode's recommended behavior regardless of font. </p> <div class="mw-heading mw-heading3"><h3 id="Bidirectional_neutral_formatting">Bidirectional neutral formatting</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Universal_Character_Set_characters&action=edit&section=9" title="Edit section: Bidirectional neutral formatting"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Writing direction is the direction glyphs are placed on the page in relation to forward progression of characters in the Unicode string. English and other languages of Latin script have left-to-right writing direction. Several major writing scripts, such as <a href="/wiki/Arabic_alphabet" title="Arabic alphabet">Arabic</a> and <a href="/wiki/Hebrew_alphabet" title="Hebrew alphabet">Hebrew</a>, have right-to-left writing direction. The Unicode specification assigns a <i>directional type</i> to each character to inform text processors how sequences of characters should be ordered on the page. </p><p>While lexical characters (that is, letters) are normally specific to a single writing script, some symbols and punctuation marks are used across many writing scripts. Unicode could have created duplicate symbols in the repertoire that differ only by directional type, but chose instead to unify them and assign them a neutral directional type. They acquire direction at render time from adjacent characters. Some of these characters also have a <i>bidi-mirrored</i> property indicating the glyph should be rendered in mirror-image when used in right-to-left text. </p><p>The render-time directional type of a neutral character can remain ambiguous when the mark is placed on the boundary between directional changes. To address this, Unicode includes characters that have strong directionality, have no glyph associated with them, and are ignorable by systems that do not process bidirectional text: </p> <ul><li>Arabic letter mark (U+061C)</li> <li>Left-to-right mark (U+200E)</li> <li>Right-to-left mark (U+200F)</li></ul> <p>Surrounding a bidirectionally neutral character by the left-to-right mark will force the character to behave as a left-to-right character while surrounding it by the right-to-left mark will force it to behave as a right-to-left character.

This distinction is not always unambiguous; however, a few examples will help illustrate the distinction. Often two characters may be combined typographically to improve the readability of the text. For example, the three letter sequence "ffi" may be treated as a single glyph. Other character sets would often assign a code point to this glyph in addition to the individual letters: "f" and "i". </p><p>In addition, Unicode approaches <a href="/wiki/Diacritic" title="Diacritic">diacritic</a> modified letters as separate characters that, when rendered, become a single glyph. For example, an "o" with <a href="/wiki/Diaeresis_(diacritic)" title="Diaeresis (diacritic)">diaeresis</a>: "<a href="/wiki/%C3%96" title="Ö">ö</a>". Traditionally, other character sets assigned a unique character code point for each diacritic modified letter used in each language. Unicode seeks to create a more flexible approach by allowing combining diacritic characters to combine with any letter. This has the potential to significantly reduce the number of active code points needed for the character set. As an example, consider a language that uses the Latin script and combines the diaeresis with the upper- and lower-case letters "a", "o", and "u". With the Unicode approach, only the diaeresis diacritic character needs to be added to the character set to use with the Latin letters: "a", "A", "o", "O", "u", and "U": seven characters in all. A legacy character sets needs to add six <b>precomposed</b> letters with a diaeresis in addition to the six code points it uses for the letters without diaeresis: twelve character code points in total. </p> <div class="mw-heading mw-heading3"><h3 id="Compatibility_characters">Compatibility characters</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Universal_Character_Set_characters&action=edit&section=28" title="Edit section: Compatibility characters"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>UCS includes thousands of characters that Unicode designates as compatibility characters. These are characters that were included in UCS in order to provide distinct code points for characters that other character sets differentiate, but would not be differentiated in the Unicode approach to characters. </p><p>The chief reason for this differentiation was that Unicode makes a distinction between characters and glyphs. For example, when writing English in a <a href="/wiki/Cursive" title="Cursive">cursive</a> style, the letter "i" may take different forms whether it appears at the beginning of a word, the end of a word, the middle of a word or in isolation. Languages such as <a href="/wiki/Arabic" title="Arabic">Arabic</a> written in an Arabic script are always cursive. Each letter has many different forms. UCS includes 730 Arabic form characters that decompose to just 88 unique Arabic characters. However, these additional Arabic characters are included so that text processing software may translate text from other character sets to UCS and back again without any loss of information crucial for non-Unicode software. </p><p>However, for UCS and Unicode in particular, the preferred approach is to always encode or map that letter to the same character no matter where it appears in a word. Then the distinct forms of each letter are determined by the font and text layout software methods. In this way, the internal memory for the characters remains identical regardless of where the character appears in a word. This greatly simplifies searching, sorting and other text processing operations. </p> <div class="mw-heading mw-heading2"><h2 id="Character_properties">Character properties</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Universal_Character_Set_characters&action=edit&section=29" title="Edit section: Character properties"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Unicode_character_property" title="Unicode character property">Unicode character property</a></div> <p>Every character in Unicode is defined by a large and growing set of properties.
