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 ...
(1) The overall process for internationalization and localization of software products. (2) a synonym for internationalization. Also known by the abbreviation "g11n". Note that the meaning of "globalization" which is relevant to software products should be distinguished from the more widespread use of "globalization" in the context of economics.

(1) An abstract form that represents one or more glyph images. (2) A synonym for glyph image. In displaying Unicode character data, one or more glyphs may be selected to depict a particular character. These glyphs are selected by a rendering engine during composition and layout processing.
Industry:Computer; Software
A numeric code that refers to a glyph. Usually, the glyphs contained in a font are referenced by their glyph code. Glyph codes may be local to a particular font; that is, a different font containing the same glyphs may use different codes.
Industry:Computer; Software
Similar to a glyph code, a glyph identifier is a label used to refer to a glyph within a font. A font may employ both local and global glyph identifiers.
Industry:Computer; Software
The actual, concrete image of a glyph representation having been rasterized or otherwise imaged onto some display surface.
Industry:Computer; Software
A collection of properties that specify the relative size and positioning along with other features of a glyph.

(1) A minimally distinctive unit of writing in the context of a particular writing system. For example, ‹b› and ‹d› are distinct graphemes in English writing systems because there exist distinct words like big and dig. Conversely, a lowercase italiform letter a and a lowercase Roman letter a are not distinct graphemes because no word is distinguished on the basis of these two different forms. (2) What a user thinks of as a character.

A character with the property Grapheme_Base, or any standard Korean syllable block.
* Characters with the property Grapheme_Base include all base characters (with the exception of U+FF9E..U+FF9F) plus most spacing marks.
* The concept of a grapheme base is introduced to simplify discussion of the graphical application of nonspacing marks to other elements of text. A grapheme base may consist of a spacing (combining) mark, which distinguishes it from a base character per se. A grapheme base may also itself consist of a sequence of characters, in the case of the standard Korean syllable block.

The text between grapheme cluster boundaries as specified by Unicode Standard Annex #29, “Unicode Text Segmentation.” A grapheme cluster represents a horizontally segmentable unit of text, consisting of some grapheme base (which may consist of a Korean syllable) together with any number of nonspacing marks applied to it.
* This definition of “grapheme cluster” is generic. The specification of grapheme cluster boundary segmentation in UAX #29 includes two alternatives, for “extended grapheme clusters” and for “legacy grapheme clusters.” Furthermore, the segmentation algorithm in UAX #29 is tailorable.
* The grapheme cluster represents a horizontally segmentable unit of text, consisting of some grapheme base (which may consist of a Korean syllable) together with any number of nonspacing marks applied to it.
* A grapheme cluster is similar, but not identical to a combining character sequence. A combining character sequence starts with a base character and extends across any subsequent sequence of combining marks, nonspacing or spacing. A combining character sequence is most directly relevant to processing issues related to normalization, comparison, and searching.
* A grapheme cluster typically starts with a grapheme base and then extends across any subsequent sequence of nonspacing marks. A grapheme cluster is most directly relevant to text rendering and processes such as cursor placement and text selection in editing, but may also be relevant to comparison and searching.
* For many processes, a grapheme cluster behaves as if it were a single character with the same properties as its grapheme base. Effectively, nonspacing marks apply graphically to the base, but do not change its properties. For example, <x, macron> behaves in line breaking or bidirectional layout as if it were the character x.
