+Core Perl now mostly works on EBCDIC platforms.   This is not true of

+As a result of this, certain C<XS> functions are now deprecated; see

+Certain rarely used functions and macros available to C<XS> code are
+now, or are planned to be deprecated.  These are:
+C<utf8n_to_uvuni> (use C<utf8_to_uvchr_buf> instead),
+C<utf8_to_uni_buf> (use C<utf8_to_uvchr_buf> instead),
+C<valid_utf8_to_uvuni> (use C<utf8_to_uvchr_buf> instead),
+C<uvuni_to_utf8> (use C<uvchr_to_utf8> instead),
+C<NATIVE_TO_NEED> (this did not work properly anyway),
+and C<ASCII_TO_NEED>  (this did not work properly anyway).
+
+Starting in this release, almost never does application code need to
+distinguish between the platform's character set and Latin1, on which the
+lowest 256 characters of Unicode are based.
