In typography, a dingbat is an ornament, specifically, a glyph used in typesetting, often employed to create box frames, or as a dinkus. Some of the dingbat symbols have been used as signature marks or used in bookbinding to order sections.
The general prohibition sign, also known informally as the no symbol, 'do not' sign, circle-backslash symbol, nay, interdictory circle, prohibited symbol, don't do it symbol, or universal no, is a red circle with a 45-degree diagonal line inside the circle from upper-left to lower-right. It is typically overlaid on a pictogram to warn that an activity is not permitted, or has accompanying text to describe what is prohibited.
An emoji is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages. The primary function of modern emoji is to fill in emotional cues otherwise missing from typed conversation as well as to replace words as part of a logographic system. Emoji exist in various genres, including facial expressions, expressions, activity, food and drinks, celebrations, flags, objects, symbols, places, types of weather, animals and nature.
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.
Lucida is an extended family of related typefaces designed by Charles Bigelow and Kris Holmes and released from 1984 onwards. The family is intended to be extremely legible when printed at small size or displayed on a low-resolution display – hence the name, from 'lucid'.
Webdings is a TrueType dingbat typeface developed in 1997. It was initially distributed with Internet Explorer 4.0, then as part of Core fonts for the Web, and is included in all versions of Microsoft Windows since Windows 98. All of the pictographic Webding glyphs that were not unifiable with existing Unicode characters were added to the Unicode Standard when version 7.0 was released in June 2014.
Marlett is a TrueType font that has been used in Microsoft Windows since Windows 95. The operating system uses this font to create user interface icons that are used in the menus and windows. Examples are the close, maximize and minimize buttons that are made from the individual glyphs in the font. This was important to allow the users to scale the user interface and have the icons scale with the elements.
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.
ITC Zapf Dingbats is one of the more common dingbat typefaces. It was designed by the typographer Hermann Zapf in 1978 and licensed by International Typeface Corporation.
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.
Apple's Macintosh computer supports a wide variety of fonts. This support was one of the features that initially distinguished it from other systems.
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.
Miscellaneous Symbols and Pictographs is a Unicode block containing meteorological and astronomical symbols, emoji characters largely for compatibility with Japanese telephone carriers' implementations of Shift JIS, and characters originally from the Wingdings and Webdings fonts found in Microsoft Windows.
Dingbats is a Unicode block containing dingbats. Most of its characters were taken from Zapf Dingbats; it was the Unicode block to have imported characters from a specific typeface; Unicode later adopted a policy that excluded symbols with "no demonstrated need or strong desire to exchange in plain text", and thus no further dingbat typefaces were encoded until Webdings and Wingdings were encoded in Version 7.0. Some ornaments are also an emoji, having optional presentation variants.
Noto is a free font family comprising over 100 individual computer 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.
Geometric Shapes Extended is a Unicode block containing Webdings/Wingdings symbols, mostly different weights of squares, crosses, and saltires, and different weights of variously spoked asterisks, stars, and various color squares and circles for emoji.
Ornamental Dingbats is a Unicode block containing ornamental leaves, punctuation, and ampersands, quilt squares, and checkerboard patterns. It is a subset of dingbat fonts Webdings, Wingdings, and Wingdings 2.
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.
W.D. Gaster, or simply Gaster, is a character from the 2015 video game Undertale who was the previous "royal scientist" for the game's underground kingdom of monsters before he vanished mysteriously. He cannot normally be encountered in the game, and is never discussed directly as part of the game's main narrative. Players can only encounter events related to him either by luck or by modifying certain game files. A sprite from one of these events, internally named "Mystery Man", is generally used to portray W.D. Gaster, though the sprite's connection to the character is not confirmed.
