1 The utf8data.h file in this directory is generated from the Unicode
2 Character Database for version 12.1.0 of the Unicode standard.
4 The full set of files can be found here:

10 The URL's listed below are not stable. That's because Unicode 12.1.0
11 has not been officially released yet; it is scheduled to be released
12 on May 8, 2019. We taking Unicode 12.1.0 a few weeks early because it
13 contains a new Japanese character which is required in order to
14 specify Japenese dates after May 1, 2019, when Crown Prince Naruhito
15 ascends to the Chrysanthemum Throne. (Isn't internationalization fun?
16 The abdication of Emperor Akihito of Japan is requiring dozens of
17 software packages to be updated with only a month's notice. :-)
19 We will update the URL's (and any needed changes to the checksums)
20 after the final Unicode 12.1.0 is released.

53 To update to the newer version of the Unicode standard, the latest
54 released version of the UCD can be found here:
56 http://www.unicode.org/Public/UCD/latest/
58 Then, build under fs/unicode/ with REGENERATE_UTF8DATA=1:
60 make REGENERATE_UTF8DATA=1 fs/unicode/
62 After sanity checking the newly generated utf8data.h file (the
63 version generated from the 12.1.0 UCD should be 4,109 lines long, and
64 have a total size of 324k) and/or comparing it with the older version
65 of utf8data.h_shipped, rename it to utf8data.h_shipped.
67 If you are a kernel developer updating to a newer version of the
68 Unicode Character Database, please update this README.utf8data file
69 with the version of the UCD that was used, the md5sum and sha1sums of
70 the *.txt files, before checking in the new versions of the utf8data.h
71 and README.utf8data files.
