Videotex Character Set
The character sets used by Videotex are based, to greater or lesser extents, on ISO/IEC 2022. Three Data Syntax systems are defined by ITU T.101, corresponding to the Videotex systems of different countries. Data Syntax 1 Data Syntax 1 is defined in Annex B of T.101:1994. It is based on the CAPTAIN system used in Japan. Its graphical sets include JIS X 0201 and JIS X 0208. The following G-sets are available through ISO/IEC 2022-based designation escapes: Mosaic sets for Data Syntax 1 The mosaic sets supply characters for use in semigraphics. � Not in Unicode Data Syntax 2 Data Syntax 2 is defined in Annex C of T.101:1994. It corresponds to some European Videotex systems such as CEPT T/CD 06-01. The graphical character coding of Data Syntax 2 is based on T.51. The default G2 set of Data Syntax 2 is based on an older version of T.51, lacking the non-breaking space, soft hyphen, not sign ( ¬) and broken bar ( ¦) present in the current version, but adding a ...

Slash (punctuation)
The slash is a slanting line punctuation mark . It is also known as a stroke, a solidus, a forward slash and #Alternative names, several other historical or technical names. Once used as the equivalent of the modern full stop, period and comma, the slash is now used to represent #Division, division and #Fractions, fractions, as a #Dating, date separator, or to connect alternative terms. A slash in the reverse direction is known as a backslash. History Slashes may be found in early writing as a variant form of dash (typography), dashes, vertical bar, vertical strokes, etc. The present use of a slash distinguished from such other marks derives from the medieval European #virgule, virgule (, which was used as a full stop, period, #scratch, scratch comma, and caesura mark. (The first sense was eventually lost to the full stop, low dot and the other two developed separately into the comma and caesura mark ) Its use as a comma became especially widespread in Kingdom of France, Fr ...

Tilde
The tilde (, also ) is a grapheme or with a number of uses. The name of the character came into English from Spanish , which in turn came from the Latin , meaning 'title' or 'superscription'. Its primary use is as a diacritic (accent) in combination with a base letter. Its freestanding form is used in modern texts mainly to indicate approximation. History Use by medieval scribes The tilde was originally one of a variety of marks written over an omitted letter or several letters as a scribal abbreviation (a "mark of contraction"). Thus, the commonly used words ''Anno Domini'' were frequently abbreviated to ''Ao Dñi'', with an elevated terminal with a contraction mark placed over the "n". Such a mark could denote the omission of one letter or several letters. This saved on the expense of the scribe's labor and the cost of vellum and ink. Medieval European charters written in Latin are largely made up of such abbreviated words with contraction marks and other abbreviations ...

Circumflex
The circumflex () is a diacritic in the Latin and Greek scripts that is also used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from "bent around"a translation of the (). The circumflex in the Latin script is chevron-shaped (), while the Greek circumflex may be displayed either like a tilde () or like an inverted breve (). For the most commonly encountered uses of the accent in the Latin alphabet, precomposed characters are available. In English, the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language (for example '' entrepôt, crème brûlée''). In mathematics and statistics, the circumflex diacritic is sometimes used to denote a function and is called a '' hat operator''. A free-standing version of the circumflex symbol, , is encoded in ASCII and Unicode and has become known as '' caret'' and has acquired special uses, particularly i ...

Acute Accent
The acute accent (), , is a diacritic used in many modern written languages with alphabets based on the Latin alphabet, Latin, Cyrillic script, Cyrillic, and Greek alphabet, Greek scripts. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available. Uses History An early precursor of the acute accent was the Apex (diacritic), apex, used in Latin language, Latin inscriptions to mark vowel length, long vowels. The acute accent was first used in French in 1530 by Geoffroy Tory, the royal printer. Pitch Ancient Greek The acute accent was first used in the Greek diacritics, polytonic orthography of Ancient Greek, where it indicated a syllable with a high pitch accent, pitch. In Modern Greek, a stress (linguistics), stress accent has replaced the pitch accent, and the acute marks the stressed syllable of a word. The Greek name of the accented syllable was and is (''oxeîa'', Modern Greek ''oxía'') "sharp" or "h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grave Accent
The grave accent () ( or ) is a diacritical mark used to varying degrees in French, Dutch, Portuguese, Italian, Catalan and many other Western European languages as well as for a few unusual uses in English. It is also used in other languages using the Latin alphabet, such as Mohawk and Yoruba, and with non-Latin writing systems such as the Greek and Cyrillic alphabets and the Bopomofo or Zhuyin Fuhao semi-syllabary. It has no single meaning, but can indicate pitch, stress, or other features. For the most commonly encountered uses of the accent in the Latin and Greek alphabets, precomposed characters are available. For less-used and compound diacritics, a combining character facility is available. A free-standing version of the symbol (), commonly called a backtick, also exists and has acquired other uses. Uses Pitch The grave accent first appeared in the polytonic orthography of Ancient Greek to mark a lower pitch than the high pitch of the acute accent. In ...

One Half
One half is the multiplicative inverse of 2. It is an irreducible fraction with a numerator of 1 and a denominator of 2. It often appears in mathematical equations, recipes and measurements. As a word One half is one of the few fractions which are commonly expressed in natural languages by suppletion rather than regular derivation. In English, for example, compare the compound "one half" with other regular formations like "one-sixth". A ''half'' can also be said to be one part of something divided into two equal parts. It is acceptable to write one half as a hyphenated word, ''one-half''. Mathematics One half is the rational number that lies midway between 0 and 1 on the number line. Multiplication by one half is equivalent to division by two, or "halving"; conversely, division by one half is equivalent to multiplication by two, or "doubling". A number raised to the power of one half is equal to its square root. The area of a triangle is one half its bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraction (mathematics)
A fraction (from , "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A ''common'', ''vulgar'', or ''simple'' fraction (examples: and ) consists of an integer numerator, displayed above a line (or before a slash like ), and a division by zero, non-zero integer denominator, displayed below (or after) that line. If these integers are positive, then the numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. For example, in the fraction , the numerator 3 indicates that the fraction represents 3 equal parts, and the denominator 4 indicates that 4 parts make up a whole. The picture to the right illustrates of a cake. Fractions can be used to represent ratios and division (mathematics), division. Thus the fraction can be used to ...

Section Sign
The section sign (§) is a typographical character for referencing individually numbered sections of a document; it is frequently used when citing sections of a legal code. It is also known as the section symbol, section mark, double-s, or silcrow. In other languages it may be called the "paragraph symbol" (for example, ). The section sign typically appears akin to a letter S stacked on top of another S. Use The section sign is often used when referring to a specific section of a legal code. For example, in Bluebook style, "Title 16 of the United States Code Section 580p" becomes "16 U.S.C. §580p". The section sign is frequently used along with the ''pilcrow'' (or ''paragraph sign''), , to reference a specific paragraph within a section of a document. While is usually read in spoken English as the word "section", many other languages use the word "paragraph" exclusively to refer to a section of a document (especially of legal text), and use other words to describe a p ...

Number Sign
The symbol is known as the number sign, hash, (or in North America) the pound sign. The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a Typographic ligature, ligatured abbreviation for Pound (mass), pounds avoirdupois – having been derived from the now-rare . Since 2007, widespread usage of the symbol to introduce metadata tags on social media platforms has led to such tags being known as "hashtags", and from that, the symbol itself is sometimes called a hashtag. The symbol is distinguished from similar symbols by its combination of level horizontal strokes and right-tilting vertical strokes. History It is believed that the symbol traces its origins to the symbol , an abbreviation of the Roman term ''Roman pound, libra pondo'', which translates as "pound weight". The abbreviation "lb" was printed as a dedicated Ligature (writing), ligature including a horizontal line across (which indicated abbreviation ...

Dollar Sign
The dollar sign, also known as the peso sign, is a currency symbol consisting of a Letter case, capital crossed with one or two vertical strokes ( or depending on typeface), used to indicate the unit of various currency, currencies around the world, including most currencies denominated "dollar" or "peso". The explicitly double-barred sign is called cifrão in the Portuguese language. The sign is also used in several compound currency symbols, such as the Brazilian real (R$) and the United States dollar (US$): in local use, the nationality prefix is usually omitted. In countries that have other currency symbols, the US dollar is often assumed and the "US" prefix omitted. The one- and two-stroke versions are often considered mere stylistic (typeface) variants, although in some places and epochs one of them may have been specifically assigned, by law or custom, to a specific currency. The Unicode computer encoding standard defines a single code for both. In most English l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pound Sign
The pound sign () is the currency symbol, symbol for the pound unit of account, unit of Pound sterling, sterling – the currency of the United Kingdom and its associated Crown Dependencies and British Overseas Territories and previously of Kingdom of Great Britain, Great Britain and of the Kingdom of England. The same symbol is used for other currencies called pound (currency), pound, such as the Egyptian pound, Egyptian and Syrian pound, Syrian pounds. The sign may be drawn with one or two bars depending on personal preference, but the Bank of England has used the one-bar style exclusively on banknotes since 1975. In the United States, "pound sign" refers to the symbol (number sign). In Canada, "pound sign" can mean or . Origin The symbol derives from the upper case Latin letter , representing ''libra pondo'', the basic unit of weight in the Roman Empire, which in turn is derived from the Latin word ''libra'', meaning Weighing scale, scales or a balance.
