Ö, or ö, is a character that represents either a letter from several extended Latin alphabets, or the letter "o" modified with an umlaut or diaeresis. Ö, or ö, is a variant of the letter O. In many languages, the letter "ö", or the "o" modified with an umlaut, is used to denote the close-or open-mid front rounded vowels ⓘ or ⓘ.
Umlaut (/ ˈ ʊ m l aʊ t /) is a name for the two dots diacritical mark ( ̈) as used to indicate in writing (as part of the letters ä , ö , and ü ) the result of the historical sound shift due to which former back vowels are now pronounced as front vowels (for example , , and as , , and ).
For example, U+00F6 ö LATIN SMALL LETTER O WITH DIAERESIS represents both o-umlaut and o-diaeresis, while similar codes are used to represent all such cases. Unicode encodes a number of cases of "letter with a two dots diacritic" as precomposed characters and these are displayed below. (Unicode uses the term "Diaeresis" for all two-dot ...
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name.
The rationale behind this is that it enables design and usage of special mathematical characters that include all necessary properties to differentiate from other alphanumerics, e.g. in mathematics an italic "𝐴" can have a different meaning from a roman letter "A".
