Hi -

In the spirit of the day, and about as relevant to this WG as some
of the recent barely-topical posting to this mailing list...

> ISO-10646 defines a large character set called the Universal
> Character Set (UCS), which encompasses most of the world's writing
> systems.  The same set of codepoints is defined by Unicode, which
> further defines additional character properties and other
> implementation details.  By policy of the relevant standardization
> committees, changes to Unicode and amendments and additions to
> ISO/IEC 646 track each other, so that the character repertoires and
> code point assignments remain in synchronization.

> The current representation formats for Unicode (UTF-7, UTF-8, UTF-16)
> are not storage and computation efficient on platforms that utilize
> the 9 bit nonet as a natural storage unit instead of the 8 bit octet.
>
> This document describes a transformation format of Unicode that takes
> advantage of the nonet so that the format will be storage and
> computation efficient.
