TeX, stylized within the system as TeX, is a typesetting program which was designed and written by computer scientist and Stanford University professor Donald Knuth and first released in 1978. The term now refers to the system of extensions - which includes software programs called TeX engines, sets of TeX macros, and packages which provide extra typesetting functionality - built around the original TeX language. TeX is a popular means of typesetting complex mathematical formulae; it has been noted as one of the most sophisticated digital typographical systems.
The hyphen‐ is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation. Son-in-law is an example of a hyphenated word.
In publishing and graphic design, Lorem ipsum is a placeholder text commonly used to demonstrate the visual form of a document or a typeface without relying on meaningful content. Lorem ipsum may be used as a placeholder before the final copy is available. It is also used to temporarily replace text in a process called greeking, which allows designers to consider the form of a webpage or publication, without the meaning of the text influencing the design.
A newline is a control character or sequence of control characters in character encoding specifications such as ASCII, EBCDIC, Unicode, etc. This character, or a sequence of characters, is used to signify the end of a line of text and the start of a new one.
In the written form of many languages, indentation describes empty space, a.k.a. white space, used around text to signify an important aspect of the text such as:
In computing and typesetting, a soft hyphen or syllable hyphen, is a code point reserved in some coded character sets for the purpose of breaking words across lines by inserting visible hyphens if they fall on the line end but remain invisible within the line.
In word processing and digital typesetting, a non-breaking space, also called NBSP, required space, hard space, or fixed space, is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive whitespace characters from collapsing into a single space. Non-breaking space characters with other widths also exist.
Syllabification or syllabication, also known as hyphenation, is the separation of a word into syllables, whether spoken, written or signed.
The hyphen-minus symbol - is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash so it is also used for these. The name hyphen-minus derives from the original ASCII standard, where it was called hyphen–(minus). The character is referred to as a hyphen, a minus sign, or a dash according to the context where it is being used.
In typesetting and page layout, alignment or range is the setting of text flow or image placement relative to a page, column (measure), table cell, or tab.
A whitespace character is a character data element that represents white space when text is rendered for display by a computer.
In a written or published work, an initial is a letter at the beginning of a word, a chapter, or a paragraph that is larger than the rest of the text. The word is ultimately derived from the Latin initiālis, which means of the beginning. An initial is often several lines in height, and, in older books or manuscripts, may take the form of an inhabited or historiated initial. Certain important initials, such as the Beatus initial, or B, of Beatus vir... at the opening of Psalm 1 at the start of a vulgate Latin. These specific initials in an illuminated manuscript were also called initia.
The fmt command in Unix, Plan 9, Inferno, and Unix-like operating systems is used to format natural language text for humans to read.
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.
The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline. The most common versions are the en dash–, generally longer than the hyphen but shorter than the minus sign; the em dash—, longer than either the en dash or the minus sign; and the horizontal bar―, whose length varies across typefaces but tends to be between those of the en and em dashes.
The zero-width space is a non-printing character used in computerized typesetting to indicate word boundaries to text-processing systems for scripts that do not use explicit spacing, or after characters not followed by a visible space after which there may be a line break.
fold is a Unix command used for making a file with long lines more readable on a limited width computer terminal by performing a line wrap.
The Unicode Standard assigns various properties to each Unicode character and code point.
In typography, a thin space is a space character whose width is usually 1⁄5 or 1⁄6 of an em. It is used to add a narrow space, such as between nested quotation marks or to separate glyphs that interfere with one another. It is not as narrow as the hair space. It is also used in the International System of Units and in many countries as a thousands separator when writing numbers in groups of three digits, in order to facilitate reading.
The Knuth–Plass algorithm is a line-breaking algorithm designed for use in Donald Knuth's typesetting program TeX. It integrates the problems of text justification and hyphenation into a single algorithm by using a discrete dynamic programming method to minimize a loss function that attempts to quantify the aesthetic qualities desired in the finished output.
