Dear Unicoders,
I was recently pointed to the document "Character Entities: An XML Core WG View
A consensus statement from the XML Core WG as of 2002 October 23"
available at http://www.w3.org/XML/Core/2002/10/charents-20021023. In
the last paragraph, it says:
<quote>
The appropriate way to make use of such characters is to define
character entities which give human-readable names to the PUA
characters for use in authoring. The question of supplying
machine-understandable semantics for PUA characters is an open
research question: the Unicode defaults treat PUA characters like
ideographs, since the most frequent use for them is to represent
unusual ideographs for use in personal names.
</quote>
Leaving aside the red light that flashed in my head on the notion of
the W3C recommending PUA (for interchange?), I was wondering about the
notion of PUA characters being by "Unicode defaults" treated as
ideographs. Is there a canonical reference for this?
Just wondering,
All the best,
Christian Wittern
