TrueType is an outline font standard developed by Apple in the late 1980s as a competitor to Adobe's Type 1 fonts used in PostScript. It has become the most common format for fonts on the classic Mac OS, macOS, and Microsoft Windows operating systems.
OpenType is a format for scalable computer fonts. Derived from TrueType, it retains TrueType's basic structure but adds many intricate data structures for describing typographic behavior. OpenType is a registered trademark of Microsoft Corporation.
Arial is a sans-serif typeface 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. In Office 2007, Arial was replaced by Calibri as the default typeface in PowerPoint, Excel, and Outlook.
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.
Wingdings is a series of dingbat fonts that render letters as a variety of symbols. They were originally developed in 1990 by Microsoft by combining glyphs from Lucida Icons, Arrows, and Stars licensed from Charles Bigelow and Kris Holmes. Certain versions of the font's copyright string include attribution to Type Solutions, Inc., the maker of a tool used to hint the font.
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Charles Trevelyan, William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars.
Apple Inc. uses a large variety of typefaces in its marketing, operating systems, and industrial design with each product cycle. These change throughout the years with Apple's change of style in their products. This is evident in the design and marketing of the company. The current logo is a white apple with a bite out of it, which was first utilized in 2013.
The Command key, ⌘, formerly also known as the Apple key or open Apple key, is a modifier key present on Apple keyboards. The Command key's purpose is to allow the user to enter keyboard commands in applications and in the system. An "extended" Macintosh keyboard—the most common type—has two command keys, one on each side of the space bar; some compact keyboards have one only on the left.
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.
In Unicode, a Private Use Area (PUA) is a range of code points that, by definition, will not be assigned characters by the standard. Three private use areas are defined: one in the Basic Multilingual Plane, and one each in, and nearly covering, planes 15 and 16. They are intentionally left undefined so that third parties may assign their own characters without conflicting with Unicode Consortium assignments. Under the Unicode Stability Policy, the Private Use Areas will remain allocated for that purpose in all future Unicode versions.
Segoe is a typeface, or family of fonts, that is best known for its use by Microsoft. The company uses Segoe in its online and printed marketing materials, including recent logos for a number of products. Additionally, the Segoe UI font sub-family is used by numerous Microsoft applications, and may be installed by applications. It was adopted as Microsoft's default operating system font, and is also used on Outlook.com, Microsoft's web-based email service. On August 23, 2012, Microsoft unveiled its new corporate logo typeset in Segoe, replacing the logo it had used for the previous 25 years.
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.
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.
Symbol is one of the four standard fonts available on all PostScript-based printers, starting with Apple's original LaserWriter (1985). It contains a complete unaccented Greek alphabet and a selection of commonly used mathematical symbols. Insofar as it fits into any standard classification, it is a serif font designed in the style of Times New Roman.
Apple's Macintosh computer supports a wide variety of fonts. This support was one of the features that initially distinguished it from other systems.
Microsoft Sans Serif is a sans-serif typeface introduced with early Microsoft Windows versions. It is the successor of MS Sans Serif, formerly Helv, a proportional bitmap font introduced in Windows 1.0. Both typefaces are very similar in design to Arial and Helvetica. The typeface was designed to match the MS Sans bitmap included in the early releases of Microsoft Windows.
MouseText is a set of 32 graphical characters designed by Bruce Tognazzini and first implemented in the Apple IIc. They were then retrofitted to the Apple IIe forming part of the Enhanced IIe upgrade. A slightly revised version was then released with the Apple IIGS.
Unicode input is method to add a specific Unicode character to a computer file; it is a common way to input characters not directly supported by a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive screen. In contrast to ASCII's 96 element character set, Unicode encodes hundreds of thousands of graphemes (characters) from almost all of the world's written languages and many other signs and symbols besides.
The implementation of emojis on different platforms took place across a three-decade period, starting in the 1990s. Today, the exact appearance of emoji is not prescribed but can vary between fonts and platforms, much like different typefaces.
