A repertoire is a type specifier for a subtype of type character.
This term is generally used when describing a collection of characters independent of their coding. Characters in repertoires are only identified by name, by glyph, or by character description.
A repertoire can contain characters from several scripts, and a character can appear in more than one repertoire.
For some examples of repertoires, see the coded character standards ISO 8859/1, ISO 8859/2, and ISO 6937/2. Note, however, that although the term "repertoire" is chosen for definitional compatibility with ISO terminology, no conforming implementation is required to use repertoires standardized by ISO or any other standards organization.
