+Perl should never have exposed certain Unicode properties that are used
+by Unicode internally and not meant to be publicly available.  Use of
+these has generated deprecated warning messages since Perl 5.12.  The

+Other_ID_Continue, Other_ID_Start, Other_Lowercase, Other_Math, and
+Other_Uppercase.

+Perl may be recompiled to include any or all of them; instructions are
