A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is a, plural aes.
O, or o, is the fifteenth letter and the fourth vowel letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is o, plural oes.
Omega is the twenty-fourth and last letter in the Greek alphabet. In the Greek numeric system/isopsephy (gematria), it has a value of 800. The word literally means "great O", as opposed to omicron, which means "little O".
Greek numerals, also known as Ionic, Ionian, Milesian, or Alexandrian numerals, is a system of writing numbers using the letters of the Greek alphabet. In modern Greece, they are still used for ordinal numbers and in contexts similar to those in which Roman numerals are still used in the Western world. For ordinary cardinal numbers, however, modern Greece uses Arabic numerals.
Omicron is the fifteenth letter of the Greek alphabet. This letter is derived from the Phoenician letter ayin: . In classical Greek, omicron represented the close-mid back rounded vowel IPA:[o] in contrast to omega which represented the open-mid back rounded vowel IPA:[ɔː] and the digraph ου which represented the long close-mid back rounded vowel IPA:[oː]. In modern Greek, both omicron and omega represent the mid back rounded vowel IPA:[o̞] or IPA:[ɔ̝]. Letters that arose from omicron include Roman O and Cyrillic O|Ю (Cyrillic)|Ю. The word literally means "little O" as opposed to "great O". In the system of Greek numerals, omicron has a value of 70.
A breve is the diacritic mark ◌̆, shaped like the bottom half of a circle. As used in Ancient Greek, it is also called brachy, βραχύ. It resembles the caron but is rounded, in contrast to the angular tip of the caron. In many forms of Latin, ◌̆ is used for a shorter, softer variant of a vowel, such as "Ĭ", where the sound is nearly identical to the English /i/.
Ø is a letter used in the Danish, Norwegian, Faroese, and Southern Sámi languages. It is mostly used to represent the mid front rounded vowels, such as and, except for Southern Sámi where it is used as an diphthong.
A ring diacritic may appear above or below letters. It may be combined with some letters of the extended Latin alphabets in various contexts.
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It was derived from the earlier Phoenician alphabet, and is the earliest known alphabetic script to have developed distinct letters for vowels as well as consonants. In Archaic and early Classical times, the Greek alphabet existed in many local variants, but, by the end of the 4th century BC, the Ionic-based Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard throughout the Greek-speaking world and is the version that is still used for Greek writing today.
O is a letter of the Cyrillic script.
The degree symbol or degree sign, °, is a glyph or symbol that is used, among other things, to represent degrees of arc, hours, degrees of temperature or alcohol proof. The symbol consists of a small superscript circle.
The internationalized domain name (IDN) homograph attack is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look alike. For example, the Cyrillic, Greek and Latin alphabets each have a letter ⟨o⟩ that has the same shape but represents different sounds or phonemes in their respective writing systems.
Ou is a ligature of the Greek letters ο and υ which was frequently used in Byzantine manuscripts. This omicron-upsilon ligature is still seen today on icon artwork in Greek Orthodox churches, and sometimes in graffiti or other forms of informal or decorative writing.
Ayin is the sixteenth letter of the Semitic scripts, including Phoenician ʿayin 𐤏, Hebrew ʿayinע, Aramaic ʿē 𐡏, Syriac ʿē ܥ, and Arabic ʿaynع.
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.
Unicode has a certain amount of duplication of characters. These are pairs of single Unicode code points that are canonically equivalent. The reason for this are compatibility issues with legacy systems.
Ø is a Scandinavian vowel letter.
Unicode supports several phonetic scripts and notation systems 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.
O, or o, is the fifteenth letter of the English alphabet.
This is a list of rare glyph variants of the Cyrillic letter O. They were proposed for inclusion into Unicode in 2007 and incorporated as in Unicode 5.1.
