To update to the newer version of the Unicode standard, the latest
released version of the UCD can be found here:

  http://www.unicode.org/Public/UCD/latest/

To build the utf8data.h file, from a kernel tree that has been built,
cd to this directory (fs/unicode) and run this command:

	make C=../.. objdir=../.. utf8data.h.new

After sanity checking the newly generated utf8data.h.new file (the
version generated from the 11.0.0 UCD should be 13,834 lines long, and
have a total size of 1104k) and/or comparing it with the older version
of utf8data.h, rename it to utf8data.h.

If you are a kernel developer updating to a newer version of the
Unicode Character Database, please update this README.utf8data file
with the version of the UCD that was used, the md5sum and sha1sums of
the *.txt files, before checking in the new versions of the utf8data.h
and README.utf8data files.
