Unicode 3.0.1 update beta data files available

The beta directory for the Unicode 3.0.1 update has been created.

Due to the current problem with anonymous ftp on www.unicode.org,
only the http version of this directory is currently available:


The updated beta files at that location for the Unicode 3.0.1 update are:

   5179 Jul 31 21:14 ArabicShaping-3d1.beta.txt
  43559 Jul 31 21:14 CaseFolding-2d1.beta.txt
   5085 Jul 31 21:14 CompositionExclusions-2d1.beta.txt
  55254 Jul 31 21:14 PropList-3.0.1d2.beta.txt
  13841 Jul 31 21:14 SpecialCasing-3d2.beta.txt
  48261 Jul 31 21:14 UnicodeData-3.0.1d1.beta.html
 636269 Jul 31 21:15 UnicodeData-3.0.1d2.beta.txt

These are temporary names. Once the beta review closes, the "beta" and
the delta number on the files will be dropped for the permanent
versioned filename, and the latest versions of the files will
be copied into the UNIDATA directory minus the version extension.

And comparable changes will be made in the ftp hierarchy as well, as
soon as regular ftp service can be restored on the server.

Before that happens, however, we would like to invite all interested
implementers to examine the data files and report any problems you
find in them, so that any problem can be corrected before the finalization
of the Unicode 3.0.1 update.

Note that UnicodeData.txt and PropList.txt now explicitly contain
codepoint listings using the 5- or 6-digit UTF-32 notation. If
you are using automated parsers on either of those files, be aware
of this change in convention and make sure your code is prepared
to handle parsing of codepoint values greater than 0xFFFF.

We are introducing this change now with the relatively trivial
listing of user-defined, unassigned, and not-a-character codepoints
past U+FFFF, so people can test out their implementations before
they get whumped with 40,000+ new characters from Planes 1, 2,
and 14 for the upcoming Unicode 3.1.
