The Unicode Consortium or Unicode Inc. is a not-for-profit organization that coordinates the development of the Unicode standard. Its stated goal is to eventually enable computers to operate in all languages from around the world. The consortium develops and publishes a list of freely-available ...
A writing system in which only consonants are indicated. The term “abjad” is derived from the first four letters of the traditional order of the Arabic script: alef, ba, jeem, dal.

A unit of information used for the organization, control, or representation of textual data.
* When representing data, the nature of that data is generally symbolic as opposed to some other kind of data (for example, aural or visual). Examples of such symbolic data include letters, ideographs, digits, punctuation, technical symbols, and dingbats.
* An abstract character has no concrete form and should not be confused with a glyph.
* An abstract character does not necessarily correspond to what a user thinks of as a “character” and should not be confused with a grapheme.
* The abstract characters encoded by the Unicode Standard are known as Unicode abstract characters.
* Abstract characters not directly encoded by the Unicode Standard can often be represented by the use of combining character sequences.

A property of abstract characters.
* Abstract character properties refer to attributes of abstract characters per se, based on their independent existence as elements of writing systems or other notational systems, irrespective of their encoding in the Unicode Standard.
* Thus the Alphabetic property, the Punctuation property, the Hex_Digit property, the Numeric_Value property, and so on are properties of abstract characters and are associated with those characters whether encoded in the Unicode Standard or in any other character encoding—or even prior to their being encoded in any character encoding standard.

An ordered sequence of one or more abstract characters.

A writing system in which consonants are indicated by the base letters that have an inherent vowel, and in which other vowels are indicated by additional distinguishing marks of some kind modifying the base letter. The term “abugida” is derived from the first four letters of the Ethiopic script in the Semitic order: alf, bet, gaml, dant.
Industry:Computer; Software
A mark placed above, below, or to the side of a character to alter its phonetic value.

(1) A mark applied or attached to a symbol to create a new symbol that represents a modified or new value. (2) A mark applied to a symbol irrespective of whether it changes the value of that symbol. In the latter case, the diacritic usually represents an independent value (for example, an accent, tone, or some other linguistic information). Also called diacritical mark or diacritical.

Denoting letters or numbers by the first letter of their name. For example, the Greek acrophonic numerals are variant forms of such initial letters.

(1) In Sanskrit grammar, the term for “letter” in general, as opposed to consonant (vyanjana) or vowel (svara). Derived from the first and last letters of the traditional ordering of Sanskrit letters—“a” and “ksha”. (2) More generally, in Indic writing systems, aksara refers to a “syllable,” consisting of a consonant plus vowel sequence, where the vowel may or may not be the inherent vowel of the consonant letter. When multiple consonants are involved, the aksara represents the entire orthographic syllable, which can include two or more leading consonants that may be visually presented in conjunct forms; in such cases, the aksara may not be identical to the phonological syllable.
Industry:Computer; Software
A term used in a broad sense in the Unicode Standard, to mean the logical description of a process used to achieve a specified result. This does not require the actual procedure described in the algorithm to be followed; any implementation is conformant as long as the results are the same.
