 Encoding the graphemes of the SignWriting Script with the x-ISWA-2010

Abstract

   For concreteness, because the universal character set is not yet
   universal, because an undocumented and unlabeled coded character set
   hampers information interchange, a 12-bit coded character set has
   been created that encodes the graphemes of the SignWriting script as
   described in the open standard of the International SignWriting
   Alphabet 2010.  The x-ISWA-2010 coded character set is defined with
   hexadecimal characters and described with Unicode characters, either
   proposed characters on plane 1 or interchange characters on plane 15.

   This memo defines a standard coded character set for the Internet
   community.  It is published for reference, examination,
   implementation, and evaluation.  Distribution of this memo is
   unlimited.
