Blackboard bold is a style of writing 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 number sets , (integers), , , and .
The Gothic alphabet is an alphabet used for writing the Gothic language. Ulfilas developed it in the 4th century AD for the purpose of translating the Bible.
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'.
Code page 437 is the character set of the original IBM PC. It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII".
Apple Symbols is a font introduced in Mac OS X 10.3 “Panther”. This is a TrueType font intended to provide coverage for characters defined as symbols in the Unicode Standard. It continues to ship with Mac OS X as part of the default installation. Prior to Mac OS X 10.5, its path was /Library/Fonts/Apple Symbols.ttf. From Mac OS X 10.5 onward, it is to be found at /System/Library/Fonts/Apple Symbols.ttf, meaning it is now considered an essential part of the system software, not to be deleted by users.
Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. These characters allow any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
New Gulim (새굴림/SaeGulRim) is a sans-serif type Unicode font designed especially for the Korean-language script, designed by HanYang System Co., Limited. It is an expanded version of Hanyang Gulrim.
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."
Symbol is one of the four standard fonts available on all PostScript-based printers, starting with Apple's original LaserWriter (1985). It contains a complete unaccented Greek alphabet and a selection of commonly used mathematical symbols. Insofar as it fits into any standard classification, it is a serif font designed in the style of Times New Roman.
Over a thousand characters from the Latin script are encoded in the Unicode Standard, grouped in several basic and extended Latin blocks. The extended ranges contain mainly precomposed letters plus diacritics that are equivalently encoded with combining diacritics, as well as some ligatures and distinct letters, used for example in the orthographies of various African languages and the Vietnamese alphabet. Latin Extended-C contains additions for Uighur and the Claudian letters. Latin Extended-D comprises characters that are mostly of interest to medievalists. Latin Extended-E mostly comprises characters used for German dialectology (Teuthonista). Latin Extended-F and -G contain characters for phonetic transcription.
In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but is nonetheless available for use as part of a text.
The Unicode Standard encodes almost all standard characters used in mathematics. Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math".
GNU FreeFont is a family of free OpenType, TrueType and WOFF vector fonts, implementing as much of the Universal Character Set (UCS) as possible, aside from the very large CJK Asian character set. The project was initiated in 2002 by Primož Peterlin and is now maintained by Steve White.
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set. The Universal Coded Character Set, most commonly called the Universal Character Set, is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other domains, to unique machine-readable data values. By creating this mapping, the UCS enables computer software vendors to interoperate, and transmit—interchange—UCS-encoded text strings from one to another. Because it is a universal map, it can be used to represent multiple languages at the same time. This avoids the confusion of using multiple legacy character encodings, which can result in the same sequence of codes having multiple interpretations depending on the character encoding in use, resulting in mojibake if the wrong one is chosen.
A numeral is a character that denotes a number. The decimal number digits 0–9 are used widely in various writing systems throughout the world, however the graphemes representing the decimal digits differ widely. Therefore Unicode includes 22 different sets of graphemes for the decimal digits, and also various decimal points, thousands separators, negative signs, etc. Unicode also includes several non-decimal numerals such as Aegean numerals, Roman numerals, counting rod numerals, Mayan numerals, Cuneiform numerals and ancient Greek numerals. There is also a large number of typographical variations of the Western Arabic numerals provided for specialized mathematical use and for compatibility with earlier character sets, such as ² or ②, and composite characters such as ½.
In the Unicode standard, a plane is a continuous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version 15.1, five of the planes have assigned code points (characters), and seven are named.
The Unicode Standard assigns various properties to each Unicode character and code point.
A number of Greek letters, variants, digits, and other symbols are supported by the Unicode character encoding standard.
