Mathematical Alphanumeric Symbols Block
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. These also may be used to differentiate between concepts that share a letter in a single problem. 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 letter "𝐴" can have a different meaning from a roman letter "A". Unicode originally included a limited set of such letter forms in its Letterlike Symbols blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Letterlike Symbols (Unicode Block)
Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike." Symbols Glyph variants Variation selectors may be used to specify chancery (U+FE00) vs roundhand (U+FE01) forms, if the font supports them: The remainder of the set is at Mathematical Alphanumeric Symbols. Block Emoji The Letterlike Symbols block contains two emoji: U+2122 and U+2139. The block has four standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the two emoji, both of which default to a text presentation. History The following Unicode-related documents record the purpose and process of defining specific characters in the Letterlike Symbols block: See also * Greek in Unicode * Latin script in Un ...

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 Handwriting, hand (style) and subtle contrast of thick and thin strokes deriving from metal Nib (pen)#Pointed nib, 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 (1527), 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 f ... [...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-centur ...

Variation Selectors
Variation Selectors is a Unicode block containing 16 variation selectors used to specify a Variant form (Unicode), glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa script, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1–VS4, VS7, 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 – VS16. Each applies to the immediately preceding character. As of Unicode 13.0: * CJK Compatibility Ideographs, CJK compatibility ideograph variation sequences contain VS1–VS3 (U+FE00–U+FE02) * CJK Unified Ideographs Extension A and CJK Unified Ide ...

Emphasis (typography)
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 Stress (linguistics)#Prosodic stress, prosody stress in speech. Methods and use The most common methods in History of Western typography, 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 spacing as well as color 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 "type color, 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 ''italic type, italics'', where the text is written in a script ...

Blackboard Bold
Blackboard bold is a style of writing Emphasis (typography), bold symbols on a blackboard by doubling certain strokes, commonly used in mathematical lectures, and the derived style of typeface used in printed mathematical texts. The style is most commonly used to represent the Set (mathematics)#Special sets of numbers in mathematics, number sets \N (natural numbers), \Z (integers), \Q (rational numbers), \R (real numbers), and \C (complex numbers). To imitate a bold typeface on a typewriter, a character can be typed over itself (called ''double-striking''); symbols thus produced are called double-struck, and this name is sometimes adopted for blackboard bold symbols, for instance in Unicode glyph names. In typography, a typeface with characters that are not solid is called ''inline'', ''handtooled'', or ''open face''. History Traditionally, various symbols were indicated by boldface in print but on blackboards and in manuscript (publishing), manuscripts "by wavy underscoring, ...

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 Typeface#Proportion, 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 had 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 Command-line interface, console font ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraktur
Fraktur () is a calligraphic hand of the Latin alphabet and any of several blackletter typefaces derived from this hand. It is designed such that the beginnings and ends of the individual strokes that make up each letter will be clearly visible, and often emphasized; in this way it is often contrasted with the curves of the Antiqua (common) typefaces where the letters are designed to flow and strokes connect together in a continuous fashion. The word "Fraktur" derives from Latin ("a break"), built from , passive participle of ("to break"), which is also the root for the English word "fracture". In non-professional contexts, the term "Fraktur" is sometimes misused to refer to ''all'' blackletter typefaces while Fraktur typefaces do fall under that category, not all blackletter typefaces exhibit the Fraktur characteristics described above. Fraktur is often characterized as "the German typeface", as it remained popular in Germany and much of Eastern Europe far longer than el ...

Cursive
Cursive (also known as joined-up writing) is any style of penmanship in which characters are written joined in a flowing manner, generally for the purpose of making writing faster, in contrast to block letters. It varies in functionality and modern-day usage across languages and regions; being used both publicly in artistic and formal documents as well as in private communication. Formal cursive is generally joined, but casual cursive is a combination of joins and pen lifts. The writing style can be further divided as "looped", "italic script, italic", or "connected". The cursive method is used with many alphabets due to infrequent pen lifting which allows increased writing speed. However, more elaborate or ornamental calligraphic styles of writing can be slower to reproduce. In some alphabets, many or all letters in a word are connected, sometimes making a word one single complex stroke.

Sans-serif
In typography and lettering, a sans-serif, sans serif (), gothic, or simply sans letterform is one that does not have extending features called "serifs" at the end of strokes. Sans-serif typefaces tend to have less stroke width variation than serif typefaces. They are often used to convey simplicity and Modern typography, modernity or minimalism. For the purposes of type classification, sans-serif designs are usually divided into these major groups: , , , , and . Sans-serif typefaces have become the most prevalent for display of text on computer screens. On lower-resolution digital displays, fine details like serifs may disappear or appear too large. The term comes from the French word , meaning "without" and "serif" of uncertain origin, possibly from the Dutch word meaning "line" or pen-stroke. In printed media, they are more commonly used for Display typeface, display use and less for body text. Before the term "sans-serif" became standard in English typography, a number of ...

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 language, German, ) or "Gothic" (although this often refers to blackletter type as well). In German usage, the term Antiqua (typeface class), Antiqua is used more broadly for serif types. Serif typefaces can be broadly classified into one of four subgroups: Serif#Old-style, Old-style, Serif#Transitional, Transitional, Serif#Didone, Didone, and Serif#Slab serif, Slab serif, in order of first emergence. Origins and etymology Serifs originated from the first official Greek writings on stone and in Latin alphabet with Roman square capitals, inscriptional lettering—words carved into s ...
