Cyrillic script

Some currency signs have derived from Cyrillic letters:

• The Ukrainian hryvnia sign (₴) is from the cursive minuscule Ukrainian Cyrillic letter He (г).
• The Russian ruble sign (₽) from the majuscule Р.
• The Kyrgyzstani som sign (⃀) from the majuscule С (es)
• The Kazakhstani tenge sign (₸) from Т
• The Mongolian tögrög sign (₮) from Т

Letters Ge, De, I, Short I, Em, Te, Tse, Be and Ve in upright (printed) and cursive (handwritten) variants. (Top is set in Georgia font, bottom in Odesa Script.)

Cyrillic uppercase and lowercase letter forms are not as differentiated as in Latin typography. Upright Cyrillic lowercase letters are essentially small capitals (with exceptions: Cyrillic ⟨а⟩, ⟨е⟩, ⟨і⟩, ⟨ј⟩, ⟨р⟩, and ⟨у⟩ adopted Western lowercase shapes, lowercase ⟨ф⟩ is typically designed under the influence of Latin ⟨p⟩, lowercase ⟨б⟩, ⟨ђ⟩ and ⟨ћ⟩ are traditional handwritten forms), although a good-quality Cyrillic typeface will still include separate small-caps glyphs.[32]

Cyrillic fonts, as well as Latin ones, have roman and italic types (practically all popular modern fonts include parallel sets of Latin and Cyrillic letters, where many glyphs, uppercase as well as lowercase, are shared by both). However, the native font terminology in most Slavic languages (for example, in Russian) does not use the words "roman" and "italic" in this sense.[33] Instead, the nomenclature follows German naming patterns:

Alternate variants of lowercase (cursive) Cyrillic letters: Б/б, Д/д, Г/г, И/и, П/п, Т/т, Ш/ш.

  Default Russian (Eastern) forms on the left.

  Alternate Bulgarian (Western) upright forms in the middle.

  Alternate Serbian/Macedonian (Southern) italic forms on the right.

See also:

• Roman type is called pryamoy shrift ("upright type") – compare with Normalschrift ("regular type") in German
• Italic type is called kursiv ("cursive") or kursivniy shrift ("cursive type") – from the German word Kursive, meaning italic typefaces and not cursive writing
• Cursive handwriting is rukopisniy shrift ("handwritten type") – in German: Kurrentschrift or Laufschrift, both meaning literally 'running type'
• A (mechanically) sloped oblique type of sans-serif faces is naklonniy shrift ("sloped" or "slanted type").
• A boldfaced type is called poluzhirniy shrift ("semi-bold type"), because there existed fully boldfaced shapes that have been out of use since the beginning of the 20th century.

Similarly to Latin fonts, italic and cursive types of many Cyrillic letters (typically lowercase; uppercase only for handwritten or stylish types) are very different from their upright roman types. In certain cases, the correspondence between uppercase and lowercase glyphs does not coincide in Latin and Cyrillic fonts: for example, italic Cyrillic ⟨т⟩ is the lowercase counterpart of ⟨Т⟩ not of ⟨М⟩.

Note: in some fonts or styles, ⟨д⟩, i.e. the lowercase italic Cyrillic ⟨д⟩, may look like Latin ⟨g⟩, and ⟨т⟩, i.e. lowercase italic Cyrillic ⟨т⟩, may look like small-capital italic ⟨T⟩.

In Standard Serbian, as well as in Macedonian,[34] some italic and cursive letters are allowed to be different, to more closely resemble the handwritten letters. The regular (upright) shapes are generally standardized in small caps form.[35]

Notes: Depending on fonts available, the Serbian row may appear identical to the Russian row. Unicode approximations are used in the faux row to ensure it can be rendered properly across all systems.

In Bulgarian typography, many lowercase letterforms may more closely resemble the cursive forms on the one hand and Latin glyphs on the other hand, e.g. by having an ascender or descender or by using rounded arcs instead of sharp corners.[36] Sometimes, uppercase letters may have a different shape as well, e.g. more triangular, Д and Л, like Greek delta Δ and lambda Λ.

Notes: Depending on fonts available, the Bulgarian row may appear identical to the Russian row. Unicode approximations are used in the faux row to ensure it can be rendered properly across all systems; in some cases, such as ж with k-like ascender, no such approximation exists.

Computer fonts typically default to the Central/Eastern, Russian letterforms, and require the use of OpenType Layout (OTL) features to display the Western, Bulgarian or Southern, Serbian/Macedonian forms. Depending on the choices of the font manufacturer, they may either be automatically activated by the local variant locl feature for text tagged with an appropriate language code, or the author needs to opt-in by activating a stylistic set ss## or character variant cv## feature. These solutions only enjoy partial support and may render with default glyphs in certain software configurations.[37]

A number of languages written in a Cyrillic alphabet have also been written in a Latin alphabet, such as Azerbaijani, Uzbek, Serbian, and Romanian (in the Republic of Moldova until 1989 and in the Danubian Principalities throughout the 19th century). After the disintegration of the Soviet Union in 1991, some of the former republics officially shifted from Cyrillic to Latin. The transition is complete in most of Moldova (except the breakaway region of Transnistria, where Moldovan Cyrillic is official), Turkmenistan, and Azerbaijan. Uzbekistan still uses both systems, and Kazakhstan has officially begun a transition from Cyrillic to Latin (scheduled to be complete by 2025). The Russian government has mandated that Cyrillic must be used for all public communications in all federal subjects of Russia, to promote closer ties across the federation. This act was controversial for speakers of many Slavic languages; for others, such as Chechen and Ingush speakers, the law had political ramifications. For example, the separatist Chechen government mandated a Latin script which is still used by many Chechens.

Countries with widespread use of the Cyrillic script:

  Sole official script

  Co-official with another script (either because the official language is biscriptal, or the state is bilingual)

  Being replaced with Latin, but is still in official use

  Legacy script for the official language, or large minority use

  Cyrillic is not widely used

Standard Serbian uses both the Cyrillic and Latin scripts. Cyrillic is nominally the official script of Serbia's administration according to the Serbian constitution;[43] however, the law does not regulate scripts in standard language, or standard language itself by any means. In practice the scripts are equal, with Latin being used more often in a less official capacity.[44]

The Zhuang alphabet, used between the 1950s and 1980s in portions of the People's Republic of China, used a mixture of Latin, phonetic, numeral-based, and Cyrillic letters. The non-Latin letters, including Cyrillic, were removed from the alphabet in 1982 and replaced with Latin letters that closely resembled the letters they replaced.[45]

There are various systems for romanization of Cyrillic text, including transliteration to convey Cyrillic spelling in Latin letters, and transcription to convey pronunciation.

Standard Cyrillic-to-Latin transliteration systems include:

• Scientific transliteration, used in linguistics, is based on the Serbo-Croatian Latin alphabet.
• The Working Group on Romanization Systems[46] of the United Nations recommends different systems for specific languages. These are the most commonly used around the world.
• ISO 9:1995, from the International Organization for Standardization.
• American Library Association and Library of Congress Romanization tables for Slavic alphabets (ALA-LC Romanization), used in North American libraries.
• BGN/PCGN Romanization (1947), United States Board on Geographic Names & Permanent Committee on Geographical Names for British Official Use).
• GOST 16876, a now defunct Soviet transliteration standard. Replaced by GOST 7.79-2000, which is based on ISO 9.
• Various informal romanizations of Cyrillic, which adapt the Cyrillic script to Latin and sometimes Greek glyphs for compatibility with small character sets.

See also Romanization of Belarusian, Bulgarian, Kyrgyz, Russian, Macedonian and Ukrainian.

Representing other writing systems with Cyrillic letters is called Cyrillization.

As of Unicode version 15.1, Cyrillic letters, including national and historical alphabets, are encoded across several blocks:

• Cyrillic: U+0400–U+04FF
• Cyrillic Supplement: U+0500–U+052F
• Cyrillic Extended-A: U+2DE0–U+2DFF
• Cyrillic Extended-B: U+A640–U+A69F
• Cyrillic Extended-C: U+1C80–U+1C8F
• Cyrillic Extended-D: U+1E030–U+1E08F
• Phonetic Extensions: U+1D2B, U+1D78
• Combining Half Marks: U+FE2E–U+FE2F

The characters in the range U+0400 to U+045F are essentially the characters from ISO 8859-5 moved upward by 864 positions. The characters in the range U+0460 to U+0489 are historic letters, not used now. The characters in the range U+048A to U+052F are additional letters for various languages that are written with Cyrillic script.

Unicode as a general rule does not include accented Cyrillic letters. A few exceptions include:

• combinations that are considered as separate letters of respective alphabets, like Й, Ў, Ё, Ї, Ѓ, Ќ (as well as many letters of non-Slavic alphabets);
• two most frequent combinations orthographically required to distinguish homonyms in Bulgarian and Macedonian: Ѐ, Ѝ;
• a few Old and New Church Slavonic combinations: Ѷ, Ѿ, Ѽ.

To indicate stressed or long vowels, combining diacritical marks can be used after the respective letter (for example, U+0301 ◌́ COMBINING ACUTE ACCENT: е́ у́ э́ etc.).

Some languages, including Church Slavonic, are still not fully supported.

Unicode 5.1, released on 4 April 2008, introduces major changes to the Cyrillic blocks. Revisions to the existing Cyrillic blocks, and the addition of Cyrillic Extended A (2DE0 ... 2DFF) and Cyrillic Extended B (A640 ... A69F), significantly improve support for the early Cyrillic alphabet, Abkhaz, Aleut, Chuvash, Kurdish, and Moksha.[48]

Other character encoding systems for Cyrillic:

• CP866 – 8-bit Cyrillic character encoding established by Microsoft for use in MS-DOS also known as GOST-alternative. Cyrillic characters go in their native order, with a "window" for pseudographic characters.
• ISO/IEC 8859-5 – 8-bit Cyrillic character encoding established by International Organization for Standardization
• KOI8-R – 8-bit native Russian character encoding. Invented in the USSR for use on Soviet clones of American IBM and DEC computers. The Cyrillic characters go in the order of their Latin counterparts, which allowed the text to remain readable after transmission via a 7-bit line that removed the most significant bit from each byte – the result became a very rough, but readable, Latin transliteration of Cyrillic. Standard encoding of early 1990s for Unix systems and the first Russian Internet encoding.
• KOI8-U – KOI8-R with addition of Ukrainian letters.
• MIK – 8-bit native Bulgarian character encoding for use in Microsoft DOS.
• Windows-1251 – 8-bit Cyrillic character encoding established by Microsoft for use in Microsoft Windows. The simplest 8-bit Cyrillic encoding – 32 capital chars in native order at 0xc0–0xdf, 32 usual chars at 0xe0–0xff, with rarely used "YO" characters somewhere else. No pseudographics. Former standard encoding in some Linux distributions for Belarusian and Bulgarian, but currently displaced by UTF-8.
• GOST-main.
• GB 2312 – Principally simplified Chinese encodings, but there are also the basic 33 Russian Cyrillic letters (in upper- and lower-case).
• JIS and Shift JIS – Principally Japanese encodings, but there are also the basic 33 Russian Cyrillic letters (in upper- and lower-case).

Each language has its own standard keyboard layout, adopted from typewriters. With the flexibility of computer input methods, there are also transliterating or phonetic/homophonic keyboard layouts made for typists who are more familiar with other layouts, like the common English QWERTY keyboard. When practical Cyrillic keyboard layouts or fonts are unavailable, computer users sometimes use transliteration or look-alike "volapuk" encoding to type in languages that are normally written with the Cyrillic alphabet.
