Animation of a half-turn ambigram of the word ambigram, with 180-degree rotational symmetry [1]. An ambigram is a calligraphic composition of glyphs (letters, numbers, symbols or other shapes) that can yield different meanings depending on the orientation of observation.
In mathematics, and especially in category theory, a commutative diagram is a diagram of objects, also known as vertices, and morphisms, also known as arrows or edges, such that when selecting two objects any directed path through the diagram leads to the same result by composition.
Many (but not all) graphemes that are part of a writing system that encodes a full spoken language are included in the Unicode standard, which also includes graphical symbols. See: Language code; List of Unicode characters; List of writing systems; Punctuation
For example, the grapheme à requires two glyphs: the basic a and the grave accent `. In general, a diacritic is regarded as a glyph, [ 2 ] even if it is contiguous with the rest of the character like a cedilla in French , Catalan or Portuguese , the ogonek in several languages, or the stroke on a Polish " Ł ".
In linguistics, a grapheme is the smallest functional unit of a writing system. [1] The word grapheme is derived from Ancient Greek gráphō ('write'), and the suffix -eme by analogy with phoneme and other emic units. The study of graphemes is called graphemics. The concept of graphemes is abstract and similar to the notion in computing of a ...
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 (abbr. UCS, official designation: ISO/IEC 10646), is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other ...

A grapheme is the basic functional unit of a writing system. Graphemes are generally defined as minimally significant elements which, when taken together, comprise the set of symbols from which texts may be constructed. [13] All writing systems require a set of defined graphemes, collectively called a script. [14]
