Background:
https://metacpan.org/pod/release/RJBS/perl-5.24.0/pod/perldelta.pod#Doing-bitwise-operations-on-strings-containing-code-points-above-0xFF-is-deprecated

http://perldoc.perl.org/perldiag.html

  Use of strings with code points over 0xFF as arguments to %s operator is deprecated

  (D deprecated) You tried to use one of the string bitwise operators
  (& or | or ^ or ~ ) on a string containing a code point over 0xFF.
  The string bitwise operators treat their operands as strings of
  bytes, and values beyond 0xFF are nonsensical in this context.


Cheers,
