Mathematical Alphanumeric Symbols
Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics. By providing uniformity over numerous mathematical articles and books, these conventions help to read mathematical formulas. Unicode now includes many such symbols (in the range U+1D400–U+1D7FF). The rationale behind this is that it enables design and usage of special mathematical characters (fonts) that include all necessary properties to differentiate from other alphanumerics, e.g. in mathematics an ''italic'' "đ´" can have a different meaning from a ''roman'' letter "A". Unicode originally included a limited set of such letter forms in its Letterlike Symbols block before completing the set of Latin and Greek letter forms in this block beginning in version ...

Script (Unicode)
In Unicode, a script is a collection of letters and other written signs used to represent textual information in one or more writing systems. Some scripts support one and only one writing system and language, for example, Armenian. Other scripts support many different writing systems; for example, the Latin script supports English, French, German, Italian, Vietnamese, Latin itself, and several other languages. Some languages make use of multiple alternate writing systems and thus also use several scripts; for example, in Turkish, the Arabic script was used before the 20th century but transitioned to Latin in the early part of the 20th century. For a list of languages supported by each script, see the list of languages by writing system. More or less complementary to scripts are symbols and Unicode control characters. The unified diacritical characters and unified punctuation characters frequently have the "common" or "inherited" script property. However, the individual s ...

Serif
In typography, a serif () is a small line or stroke regularly attached to the end of a larger stroke in a letter or symbol within a particular font or family of fonts. A typeface or "font family" making use of serifs is called a serif typeface (or serifed typeface), and a typeface that does not include them is sans-serif. Some typography sources refer to sans-serif typefaces as "grotesque" (in German, ) or "Gothic", and serif typefaces as "roman". Origins and etymology Serifs originated from the first official Greek writings on stone and in Latin alphabet with inscriptional letteringâwords carved into stone in Roman antiquity. The explanation proposed by Father Edward Catich in his 1968 book ''The Origin of the Serif'' is now broadly but not universally accepted: the Roman letter outlines were first painted onto stone, and the stone carvers followed the brush marks, which flared at stroke ends and corners, creating serifs. Another theory is that serifs were devised to neaten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roundhand
Round hand (also roundhand) is a type of handwriting and calligraphy originating in England in the 1660s primarily by the writing masters John Ayres and William Banson. Characterised by an open flowing hand (style) and subtle contrast of thick and thin strokes deriving from metal pointed nibs in which the flexibility of the metal allows the left and right halves of the point to spread apart under light pressure and then spring back together, the popularity of round hand grew rapidly, becoming codified as a standard, through the publication of printed writing manuals. Origins During the Renaissance, writing masters of the Apostolic Camera developed the '' italic cursiva'' script. When the Apostolic Camera was destroyed during the sack of Rome in 1527, many masters moved to Southern France where they began to refine the renaissance ' script into a new script, '. By the end of the 16th century, ' began to replace '. ' was further adapted into the French style ' in the ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chancery Hand
The term "chancery hand" can refer to either of two distinct styles of historical handwriting. A chancery hand was at first a form of handwriting for business transactions that developed in the Lateran chancery (the ) of the 13th century, then spread to France, notably through the Avignon Papacy, and to England after 1350. This early "chancery hand" is a form of blackletter. Versions of it were adopted by royal and ducal chanceries, which were often staffed by clerics who had taken minor orders. A later cursive "chancery hand", also developed in the Vatican but based on humanist minuscule (itself based on Carolingian minuscule), was introduced in the 1420s by Niccolò Niccoli; it was the manuscript origin of the typefaces we recognize as '' italic''. Blackletter chancery English chancery hand In medieval England each of the royal departments tended to develop its own characteristic hand: the chancery hand used in the royal chancery at Westminster from the mid-cen ...

Variation Selectors
Variation Selectors is the block name of a Unicode code point block containing 16 variation selectors. Each variation selector is used to specify a specific glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1, VS2, VS3, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively. These combining characters are named ''variation selector-1'' (for U+FE00) through to ''variation selector-16'' (U+FE0F), and are abbreviated VS1 â VS16. Each applies to the immediately preceding character. As of Unicode 13.0: * CJK compatibility ideograph variation sequences contain VS1–VS3 (U+FE00–U+FE02) * CJK Unified Ideographs Extension A and B variati ...

Italic Type
In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Owing to the influence from calligraphy, italics normally slant slightly to the right. Italics are a way to emphasise key points in a printed text, to identify many types of creative works, to cite foreign words or phrases, or, when quoting a speaker, a way to show which words they stressed. One manual of English usage described italics as "the print equivalent of underlining"; in other words, underscore in a manuscript directs a typesetter to use italic. The name comes from the fact that calligraphy-inspired typefaces were first designed in Italy, to replace documents traditionally written in a handwriting style called chancery hand. Aldus Manutius and Ludovico Arrighi (both between the 15th and 16th centuries) were the main type designers involved in this process at the time. Along with blackletter and Roman type, it served as one of the major typefaces in the history of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bold
In typography, emphasis is the strengthening of words in a text with a font in a different style from the rest of the text, to highlight them. It is the equivalent of prosody stress in speech. Methods and use The most common methods in Western typography fall under the general technique of emphasis through a change or modification of font: ''italics'', boldface and . Other methods include the alteration of LETTER CASE and as well as and *additional graphic marks*. Font styles and variants The human eye is very receptive to differences in "brightness within a text body." Therefore, one can differentiate between types of emphasis according to whether the emphasis changes the " blackness" of text, sometimes referred to as typographic color. A means of emphasis that does not have much effect on blackness is the use of ''italics'', where the text is written in a script style, or '' oblique'', where the vertical orientation of each letter of the text is slanted to the left ...

Blackboard Bold
Blackboard bold is a typeface style that is often used for certain symbols in mathematical texts, in which certain lines of the symbol (usually vertical or near-vertical lines) are doubled. The symbols usually denote number sets. One way of producing blackboard bold is to double-strike a character with a small offset on a typewriter. Thus, they are also referred to as double struck. In typography, such a font with characters that are not solid is called an "inline", "shaded", or "tooled" font. History Origin In some texts, these symbols are simply shown in bold type. Blackboard bold in fact originated from the attempt to write bold letters on blackboards in a way that clearly differentiated them from non-bold letters (by using the edge rather than the point of a chalk). It then made its way back into print form as a separate style from ordinary bold, possibly starting with the original 1965 edition of Gunning and Rossi's textbook on complex analysis.

Monospaced Font
A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with variable-width fonts, where the letters and spacings have different widths. Monospaced fonts are customary on typewriters and for typesetting computer code. Monospaced fonts were widely used in early computers and computer terminals, which often had extremely limited graphical capabilities. Hardware implementation was simplified by using a text mode where the screen layout was addressed as a regular grid of tiles, each of which could be set to display a character by indexing into the hardware's character map. Some systems allowed colored text to be displayed by varying the foreground and background color for each tile. Other effects included reverse video and blinking text. Nevertheless, these early systems were typically limited to a single console font. Even though computers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
