Arabic numeralsSymbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 Arabic numerals set in Source Sans typeface The Arabic numerals are ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) used for writing numbers. The term often also implies a positional notation number with a decimal base, in particular when contrasted with Roman numerals. However, the symbols are also used to write numbers in other bases, as well as non-quantitative identifiers such as a product model or a license plate.
English alphabetModern English is written with a Latin-script alphabet consisting of 26 letters, with each having both uppercase and lowercase forms. The word alphabet is a compound of alpha and beta, the names of the first two letters in the Greek alphabet. The earliest Old English writing during the 5th century used a runic alphabet known as the futhorc.

Dot (diacritic)Diacritical mark When used as a diacritic mark, the term dot primarily refers to the glyphs "combining dot above" (◌̇), and "combining dot below" (◌̣) which may be combined with some letters of the extended Latin alphabets in use in a variety of languages. Similar marks are used with other scripts. Overdot Language scripts or transcription schemes that use the dot above a letter as a diacritical mark: In some forms of Arabic romanization, ġ stands for ghayn (غ).
AltGr keyAltGr (also Alt Graph) is a modifier key found on computer keyboards. It is primarily used to type characters that are used less frequently in the language that the keyboard is designed for, such as foreign currency symbols, typographic marks and accented letters. The AltGr key is used to access a third and a fourth grapheme for most keys. Most are accented variants of the letters on the keys, but some are additional symbols and punctuation marks.Cork encodingThe Cork (also known as T1 or EC) encoding is a character encoding used for encoding glyphs in fonts. It is named after the city of Cork in Ireland, where during a TeX Users Group (TUG) conference in 1990 a new encoding was introduced for LaTeX. It contains 256 characters supporting most west- and east-European languages with the Latin alphabet.
Unicode subscripts and superscriptsUnicode denominator & numerator glyphs 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.
Mathematical operators and symbols in UnicodeBlackboard at the Laurent Schwartz Center for Mathematics, École Polytechnique The Unicode Standard encodes almost all standard characters used in mathematics. Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. Mathematical operators and symbols are in multiple Unicode blocks.Monaco (typeface)Monaco is a monospacedsans-seriftypeface designed by Susan Kare, Kris Holmes, and Charles Bigelow. It ships with macOS and has been present in all releases of Macintosh system software since the first Macintosh in 1984. Characters are distinct, and it is difficult to confuse 0 (figure zero) and O (uppercase O), or 1 (figure one), | (vertical bar), I (uppercase i) and l (lowercase L).IDN homograph attackAn internationalized domain name (IDN) homograph attack (also homoglyph attack) is a method used by malicious parties to deceive computer users about the identity of the remote system they are communicating with. This is achieved by exploiting the fact that many different characters look alike and the user is unlikely to spot a subtle substitution.
DiacriticModifier mark added to a letterLatin letter A with multiple diacriticsA diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greekδιακριτικός (diakritikós, "distinguishing"), from διακρίνω (diakrínō, "to distinguish"). The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective.
