Package COM.INFORMATIMAGO.COMMON-LISP.CESARUM.CHARACTER-SETS

This package exports functions to manage character-sets, character
encodings, coding systems and external format.  It's all the same, but
everyone likes to have his own terms...

The base character set repertoire will be the IANA one, published at:
http://www.iana.org/assignments/character-sets</a>


The cs-lisp-encoding and cs-emacs-encoding of the character sets are
hooked in by the implementation specific initialization code in the
COM.INFORMATIMGO.CLEXT.CHARACTER-SET package.
