Unicode, formally The Unicode Standard, is a text encoding standard maintained by the Unicode Consortium designed to support the use of text written in all of the world's major writing systems. Version 15.1 of the standard defines 149813 characters and 161 scripts used in various ordinary, literary, academic, and technical contexts.
Arial is a sans-serif typeface and set of computer fonts in the neo-grotesque style. Fonts from the Arial family are included with all versions of Microsoft Windows after Windows 3.1, as well as in other Microsoft programs, Apple's macOS, and many PostScript 3 printers.
Arial Unicode MS is a TrueType font and the extended version of the font Arial. Compared to Arial, it includes higher line height, omits kerning pairs and adds enough glyphs to cover a large subset of Unicode 2.1—thus supporting most Microsoft code pages, but also requiring much more storage space. It also adds Ideographic layout tables, but unlike Arial, it mandates no smoothing in the 14–18 point range, and contains Roman (upright) glyphs only; there is no oblique (italic) version. Arial Unicode MS was previously distributed with Microsoft Office, but this ended in 2016 version. It is bundled with Mac OS X v10.5 and later. It may also be purchased separately from Ascender Corporation, who licenses the font from Microsoft.
Michael Everson is an American and Irish linguist, script encoder, typesetter, type designer and publisher. He runs a publishing company called Evertype, through which he has published over a hundred books since 2006.
Courier is a monospaced slab serif typeface. Courier was created by IBM in the mid-1950s, and was designed by Howard "Bud" Kettler (1919–1999). The Courier name and typeface concept are in the public domain. Courier has been adapted for use as a computer font, and versions of it are installed on most desktop computers.
Computer Modern is the original family of typefaces used by the typesetting program TeX. It was created by Donald Knuth with his Metafont program, and was most recently updated in 1992. Computer Modern, or variants of it, remains very widely used in scientific publishing, especially in disciplines that make frequent use of mathematical notation.
Gentium is a Unicode serif typeface designed by Victor Gaultney. Gentium fonts are free and open source software, and are released under the SIL Open Font License (OFL), which permits modification and redistribution. Gentium has wide support for languages using the Latin, Greek, and Cyrillic alphabets, and the International Phonetic Alphabet (IPA). Gentium Plus variants released since November 2010 now include over 5,500 glyphs and advanced typographic features through OpenType and formerly Graphite.
Junicode ("Junius-Unicode") is a free old-style serif typeface developed by Peter S. Baker of the University of Virginia. The design is based on a 17th-century typeface used in Oxford, England.
There are Unicode typefaces which are open-source and designed to contain glyphs of all Unicode characters, or at least a broad selection of Unicode scripts. There are also numerous projects aimed at providing only a certain script, such as the Arabeyes Arabic font. The advantage of targeting only some scripts with a font was that certain Unicode characters should be rendered differently depending on which language they are used in, and that a font that only includes the characters a certain user needs will be much smaller in file size compared to one with many glyphs. Unicode fonts in modern formats such as OpenType can in theory cover multiple languages by including multiple glyphs per character, though very few actually cover more than one language's forms of the unified Han characters.
The slashed zero 0̷ is a representation of the Arabic digit "0" (zero) with a slash through it. The slashed zero glyph is often used to distinguish the digit "zero" ("0") from the Latin script letter "O" anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer programming, and telecommunications. It thus helps to differentiate characters that would otherwise be homoglyphs. It was commonly used during the punch card era, when programs were typically written out by hand, to avoid ambiguity when the character was later typed on a card punch.
Lucida Grande is a humanist sans-serif typeface. It is a member of the Lucida family of typefaces designed by Charles Bigelow and Kris Holmes. It is best known for its implementation throughout the macOS user interface from 1999 to 2014, as well as in other Apple software like Safari for Windows. As of OS X Yosemite, the system font was changed from Lucida Grande to Helvetica Neue. In OS X El Capitan the system font changed again, this time to San Francisco.
A fallback font is a reserve typeface containing symbols for as many Unicode characters as possible. When a display system encounters a character that is not part of the repertoire of any of the other available fonts, a symbol from a fallback font is used instead. Typically, a fallback font will contain symbols representative of the various types of Unicode characters.
Charis SIL is a transitional serif typeface developed by SIL International based on Bitstream Charter, one of the first fonts designed for laser printers. The font offers four family members: roman, bold, italic, and bold italic.
A Unicode font is a computer font that maps glyphs to code points defined in the Unicode Standard. The vast majority of modern computer fonts use Unicode mappings, even those fonts which only include glyphs for a single writing system, or even only support the basic Latin alphabet. Fonts which support a wide range of Unicode scripts and Unicode symbols are sometimes referred to as "pan-Unicode fonts", although as the maximum number of glyphs that can be defined in a TrueType font is restricted to 65,535, it is not possible for a single font to provide individual glyphs for all defined Unicode characters. This article lists some widely used Unicode fonts that support a comparatively large number and broad range of Unicode characters.
GNU FreeFont is a family of free OpenType, TrueType and WOFF vector fonts, implementing as much of the Universal Character Set (UCS) as possible, aside from the very large CJK Asian character set. The project was initiated in 2002 by Primož Peterlin and is now maintained by Steve White.
PostScript fonts are font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting. This system uses PostScript file format to encode font information.
Droid is a font family first released in 2007 and created by Ascender Corporation for use by the Open Handset Alliance platform Android and licensed under the Apache License. The fonts are intended for use on the small screens of mobile handsets and were designed by Steve Matteson of Ascender Corporation. The name was derived from the Open Handset Alliance platform named Android.
Runic is a Unicode block containing runic characters. It was introduced in Unicode 3.0 (1999), with eight additional characters introduced in Unicode 7.0 (2014). The original encoding of runes in UCS was based on the recommendations of the "ISO Runes Project" submitted in 1997.
Noto is a font family comprising over 100 individual fonts, which are together designed to cover all the scripts encoded in the Unicode standard. As of October 2016, Noto fonts cover all 93 scripts defined in Unicode version 6.1, although fewer than 30,000 of the nearly 75,000 CJK unified ideographs in version 6.0 are covered. In total, Noto fonts cover over 77,000 characters, which is around half of the 149,186 characters defined in Unicode 15.0.
