charset

Draft MDC Standard

☞

9 Character Set Profile charset

A charset is a definition of the valid characters and their characteristics available to a process. The required characteristics for a fully defined charset are:

  1. The character codes and their meaning
  2. The definition of which character codes are valid in names
  3. The available patcodes and their definitions
  4. The collation order of character strings.

Note: a charset definition is not necessarily tied to any (natural) language and could be an arbitrary set of characters or a repertoire from another set, such as ISO 10646.

The definition of the contents of standardized charsets is in Annex A. Unused charset names beginning with the initial letter Y are available for usage by M[UMPS] programmers; those beginning with the initial letter Z are reserved for vendor-defined charsets; all other charset names are reserved for future extensions to the standard.
