39To update to the newer version of the Unicode standard, the latest
40released version of the UCD can be found here:
41
42  http://www.unicode.org/Public/UCD/latest/
43
44Then, build under fs/unicode/ with REGENERATE_UTF8DATA=1:
45
46	make REGENERATE_UTF8DATA=1 fs/unicode/
47
48After sanity checking the newly generated utf8data.h file (the
49version generated from the 12.1.0 UCD should be 4,109 lines long, and
50have a total size of 324k) and/or comparing it with the older version
51of utf8data.h_shipped, rename it to utf8data.h_shipped.
52
53If you are a kernel developer updating to a newer version of the
54Unicode Character Database, please update this README.utf8data file
55with the version of the UCD that was used, the md5sum and sha1sums of
56the *.txt files, before checking in the new versions of the utf8data.h
57and README.utf8data files.
