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. A numeric character reference uses the ...
In many popular computer fonts the Unicode "superscript" and "subscript" characters are actually numerator and denominator glyphs. The intended use [ 2 ] when these characters were added to Unicode was to produce true superscripts and subscripts so that chemical and algebraic formulas could be written without markup.
The codespace is a systematic, architecture-independent representation of The Unicode Standard; actual text is processed as binary data via one of several Unicode encodings, such as UTF-8. In this normative notation, the two-character prefix U+ always precedes a written code point, [ 63 ] and the code points themselves are written as ...

Many scripts in Unicode, such as Arabic, have special orthographic rules that require certain combinations of letterforms to be combined into special ligature forms. In English, the common ampersand (&) developed from a ligature in which the handwritten Latin letters e and t (spelling et , Latin for and ) were combined. [ 1 ]
Among the fonts in widespread use, [6] [7] full implementation is provided by Segoe UI Symbol and significant partial implementation of this range is provided by Arial Unicode MS and Lucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively.
The Unicode standard does not specify or create any font (), a collection of graphical shapes called glyphs, itself.Rather, it defines the abstract characters as a specific number (known as a code point) and also defines the required changes of shape depending on the context the glyph is used in (e.g., combining characters, precomposed characters and letter-diacritic combinations).
Web pages authored using HyperText Markup Language may contain multilingual text represented with the Unicode universal character set.Key to the relationship between Unicode and HTML is the relationship between the "document character set", which defines the set of characters that may be present in an HTML document and assigns numbers to them, and the "external character encoding", or "charset ...
