Internationalization (I18N) (BC-I18)

A set of characters to be encoded.

An abstract character repertoire (ACR) is defined as an unordered set of abstract characters to be encoded, which means that they are defined by convention.

An ACR can be fixed or open. In many cases, it consists of a familiar alphabet or symbol set. Examples include:

• Japanese syllabaries and ideographs of JIS X 0208 (fixed)
• Western European alphabets and symbols of Latin-1 (fixed)
• Unicode/10646 repertoire (open)
