 The utf8data.h file in this directory is generated from the Unicode
-Character Database for version 11.0.0 of the Unicode standard.
+Character Database for version 12.1.0 of the Unicode standard.

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