# New Ticket Created by James E Keenan # Please include the string: [perl #134140] # in the subject line of all future correspondence about this issue. # <URL: https://rt.perl.org/Ticket/Display.html?id=134140 > pod/perldeprecation.pod contains this entry for perl-5.32: ##### Use of code points over 0xFF in string bitwise operators The string bitwise operators, "&", "|", "^", and "~", treat their operands as strings of bytes. As such, values above 0xFF are nonsensical. Some instances of these have been deprecated since Perl 5.24, and were made fatal in 5.28, but it turns out that in cases where the wide characters did not affect the end result, no deprecation notice was raised, and so remain legal. Now, all occurrences either are fatal or raise a deprecation warning, so that the remaining legal occurrences will be fatal in 5.32. An example of this is "" & "\x{100}" The wide character is not used in the "&" operation because the left operand is shorter. This now warns anyway. ##### This entry was made in the following commit: ##### commit ba52ce15fe5ca68de1be69e394f41ccb48a731cc Author: Karl Williamson <khw@cpan.org> Date: Tue Dec 19 16:03:39 2017 -0700 Deprecate above \xFF in bitwise string ops This is already a fatal error for operations whose outcome depends on them, but in things like "abc" & "def\x{100}" the wide character doesn't actually need to participate in the AND, and so perl doesn't. As a result of the discussion in the thread beginning with http://nntp.perl.org/group/perl.perl5.porters/244884, it was decided to deprecate these ones too. ##### Make it so.Thread Previous
