<span class="mw-page-title-main">International Phonetic Alphabet</span> System of phonetic notation

The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.

Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. These characters allow any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.

As of Unicode version 15.0, Cyrillic script is encoded across several blocks:

Combining Diacritical Marks Supplement is a Unicode block containing combining characters for the Uralic Phonetic Alphabet, Medievalist notations, and German dialectology (Teuthonista). It is an extension of the diacritic characters found in the Combining Diacritical Marks block.

Over a thousand characters from the Latin script are encoded in the Unicode Standard, grouped in several basic and extended Latin blocks. The extended ranges contain mainly precomposed letters plus diacritics that are equivalently encoded with combining diacritics, as well as some ligatures and distinct letters, used for example in the orthographies of various African languages and the Vietnamese alphabet. Latin Extended-C contains additions for Uighur and the Claudian letters. Latin Extended-D comprises characters that are mostly of interest to medievalists. Latin Extended-E mostly comprises characters used for German dialectology (Teuthonista). Latin Extended-F and -G contain characters for phonetic transcription.

Unicode supports several phonetic scripts and notations through its existing scripts and the addition of extra blocks with phonetic characters. These phonetic characters are derived from an existing script, usually Latin, Greek or Cyrillic. Apart from the International Phonetic Alphabet (IPA), extensions to the IPA and obsolete and nonstandard IPA symbols, these blocks also contain characters from the Uralic Phonetic Alphabet and the Americanist Phonetic Alphabet.

Phonetic Extensions Supplement is a Unicode block containing characters for specialized and deprecated forms of the International Phonetic Alphabet.

Latin Extended-C is a Unicode block containing Latin characters for Uighur New Script, the Uralic Phonetic Alphabet, Shona, Claudian Latin and the Swedish Dialect Alphabet.

Latin Extended-D is a Unicode block containing Latin characters for phonetic, Mayanist, and Medieval transcription and notation systems. 89 of the characters in this block are for medieval characters proposed by the Medieval Unicode Font Initiative, many of which are representative of scribal abbreviations used in Medieval manuscript texts.

Bopomofo, or Mandarin Phonetic Symbols, also named Zhuyin, is a Chinese transliteration and writing system for Mandarin Chinese and other related languages and dialects. More commonly used in Taiwanese Mandarin, it may also be used to transcribe other varieties of Chinese, particularly other varieties of Mandarin Chinese dialects, as well as Taiwanese Hokkien. Consisting of 37 characters and five tone marks, it transcribes all possible sounds in Mandarin.

Latin Extended-B is the fourth block (0180-024F) of the Unicode Standard. It has been included since version 1.0, where it was only allocated to the code points 0180-01FF and contained 113 characters. During unification with ISO 10646 for version 1.1, the block range was extended by 80 code points and another 35 characters were assigned. In version 3.0 and later, the last 60 available code points in the block were assigned. Its block name in Unicode 1.0 was Extended Latin.

IPA Extensions is a block (U+0250–U+02AF) of the Unicode standard that contains full size letters used in the International Phonetic Alphabet (IPA). Both modern and historical characters are included, as well as former and proposed IPA signs and non-IPA phonetic letters. Additional characters employed for phonetics, like the palatalization sign, are encoded in the blocks Phonetic Extensions (1D00–1D7F) and Phonetic Extensions Supplement (1D80–1DBF). Diacritics are found in the Spacing Modifier Letters (02B0–02FF) and Combining Diacritical Marks (0300–036F) blocks. Its block name in Unicode 1.0 was Standard Phonetic.

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.

Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX. Other superscript letters can be found in the Spacing Modifier Letters, Phonetic Extensions and Phonetic Extensions Supplement blocks, while the superscript 1, 2, and 3, inherited from ISO 8859-1, were included in the Latin-1 Supplement block.

Katakana Phonetic Extensions is a Unicode block containing additional small katakana characters for writing the Ainu language, in addition to characters in the Katakana block.

Shavian is a Unicode block containing characters of the Shavian alphabet, an orthography invented to write English phonetically and funded by the will of George Bernard Shaw. The Shavian block was derived from an earlier private use encoding in the ConScript Unicode Registry, like the Deseret and Phaistos Disc encodings.

Lisu is a Unicode block containing characters of the Fraser alphabet, which is used to write the Lisu language. This alphabet consists of glyphs resembling capital letters in the basic Latin alphabet in their standard form and horizontally or vertically mirrored.

Latin Extended-E is a Unicode block containing Latin script characters used in German dialectology (Teuthonista), Anthropos alphabet, Sakha and Americanist usage.

A number of Greek letters, variants, digits, and other symbols are supported by the Unicode character encoding standard.
