+=head2 Upgrade to the Unicode 6.2 beta
+
+Unicode 6.2 is proposing some changes that may very well break some CPAN
+modules.  The timing of this nicely coincides with Perl's being early in the
+release cycle.  This commit takes the current beta 6.2, adds the proposed
+changes that aren't yet in it, and subtracts the changes that would affect \X
+processing, as those turn out to have errors, and may have to be rethought.
+Unicode has been notified of these problems.
+
+This will allow us to gather data as to whether or not the proposed changes
+cause us problems.  These will be presented to Unicode to aid in their final
+decision as to whether or not to go forward with the changes.
+
+These changes will be replaced by the final version of Unicode 6.2 before
+5.18.0 is released.
