Arrows (Unicode Block)
Arrows is a Unicode block containing line, curve, and semicircle symbols terminating in barbs or arrows. Block Emoji The Arrows block contains eight emoji: U+2194–U+2199 and U+21A9–U+21AA. The block has sixteen standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji, all of which default to a text presentation. History The following Unicode-related documents record the purpose and process of defining specific characters in the Arrows block: See also *Mathematical operators and symbols in Unicode *Unicode input Unicode input is the insertion of a specific Universal Character Set characters, Unicode character on a computer by a user (computing), user; it is a common way to input characters not directly supported by a physical Keyboard (computing), keybo ...

Script (Unicode)
In Unicode, a script is a collection of Letter (alphabet), 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 Written language, language, for example, Armenian language, Armenian. Other scripts support many different writing systems; for example, the Latin script in Unicode, Latin script supports English alphabet, English, French alphabet, French, German alphabet, German, Italian alphabet, Italian, Vietnamese language, Vietnamese, Latin alphabet, 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 language, Turkish, the Ottoman Turkish alphabet, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Specials (Unicode Block)
Specials is a short Unicode block of characters allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 code points, five have been assigned since Unicode 3.0: *, marks start of annotated text *, marks start of annotating character(s) *, marks end of annotation block *, placeholder in the text for another unspecified object, for example in a compound document. * used to replace an unknown, unrecognized, or unrepresentable character * not a character. * not a character. FFFE and FFFF are not unassigned in the usual sense, but guaranteed not to be Unicode characters at all. They can be used to guess a text's encoding scheme, since any text containing these is by definition not a correctly encoded Unicode text. Unicode's character can be inserted at the beginning of a Unicode text to signal its endianness: a program reading such a text and encountering 0xFFFE would then know that it should switch the byte order for all the following characters. ...

Unicode Block
A Unicode block is one of several contiguous ranges of numeric character codes (code points) of the Unicode character set that are defined by the Unicode Consortium for administrative and documentation purposes. Typically, proposals such as the addition of new glyphs are discussed and evaluated by considering the relevant block or blocks as a whole. Each block is generally, but not always, meant to supply glyphs used by one or more specific languages, or in some general application area such as mathematics, surveying, decorative typesetting, social forums, etc. Design and implementation Unicode blocks are identified by unique names, which use only ASCII characters and are usually descriptive of the nature of the symbols, in English; such as "Tibetan" or "Supplemental Arrows-A". (When comparing block names, one is supposed to equate uppercase with lowercase letters, and ignore any whitespace, hyphens, and underbars; so the last name is equivalent to "supplemental_arrows__a" and ...

Arrow (symbol)
An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle, chevron, or concave kite, usually affixed to a line segment or rectangle, and in more complex forms a representation of an actual arrow (e.g. ➵ U+27B5). The direction indicated by an arrow is the one along the length of the line or rectangle toward the single pointed end. History An older (medieval) convention is the manicule (pointing hand, 👈). Pedro Reinel in c. 1504 first used the fleur-de-lis as indicating north in a compass rose; the convention of marking the eastern direction with a cross is older (medieval). Use of the arrow symbol does not appear to pre-date the 18th century. An early arrow symbol is found in an illustration of Bernard Forest de Bélidor's treatise ''L'architecture hydraulique'', printed in France in 1737. The arrow is here used to illustrate the direction of the flow of water and of the wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emoji
An emoji ( ; plural emoji or emojis) is a pictogram, logogram, ideogram or smiley embedded in text and used in electronic messages and web pages. The primary function of emoji is to fill in emotional cues otherwise missing from typed conversation. Examples of emoji are 😂, 😃, 🧘🏻♂️, 🌍, 🌦️, 🍞, 🚗, 📞, 🎉, ❤️, 🍆, 🍑 and 🏁. Emoji exist in various genres, including facial expressions, common objects, places and types of weather, and animals. They are much like emoticons, except emoji are pictures rather than typographic approximations; the term "emoji" in the strict sense refers to such pictures which can be represented as character encoding, encoded characters, but it is sometimes applied to Sticker (messaging), messaging stickers by extension. Originally meaning pictograph, the word ''emoji'' comes from Japanese + ; the resemblance to the English words ''emotion'' and ''emoticon'' is False cognate, purely coincidental. The I ...

Variant Form (Unicode)
A variant form is a different glyph for a character, encoded in Unicode through the mechanism of variation sequences: sequences in Unicode that consist of a base character followed by a variation selector character. A variant form usually has a very similar appearance and meaning as its base form. The mechanism is intended for variant forms where, generally, if the variant form is unavailable, displaying the base character does not change the meaning of the text, and may not even be noticeable by many readers. Unicode defines two types of variation sequences: * ''Standardized variation sequences'' defined in StandardizedVariants.txt * ''Ideographic variation sequences'' defined in the Ideographic Variation Database (IVD) Variation selector characters reside in several Unicode blocks: * Variation Selectors (16 characters abbreviated VS1–VS16) * Variation Selectors Supplement (240 characters abbreviated VS17–VS256) * Mongolian (3 characters abbreviated FVS1–FVS3) ...

Miscellaneous Symbols And Pictographs
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. Emoji The block contains 637 emoji and has 312 standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for 156 base characters. Emoji modifiers The Miscellaneous Symbols and Pictographs block has 54 emoji that represent people or body parts. For these, a set of "Emoji modifiers" are defined. These are modifier characters intended to define the skin colour to be used for the emoji, based on the Fitzpatrick scale (but conflating the two lightest skin types into one category): :U+1F3FB EMOJI MODIFIER FITZPATRICK TYPE-1-2 :U+1F3FC EMOJI MODIFIER FITZPATRICK TYPE-3 :U+1F3FD EMOJI MODIFIER FITZPATRICK TYPE-4 :U+1F3FE EMOJI MODIFIER F ...
