feature 'unicode_strings' is part of the use v5.12 feature bundle. Not
all the fixes that it includes were ready in time for 5.12. The
decision was made to put into 5.12 the ones that were ready, and to not
split the functionality into multiple features, with multiple names.
When you say 'use feature :5.12', you get whatever portion of
unicode_strings is implemented on the current version of Perl that you
are running. 5.16 is extending it even more, to change the behavior of
quotemeta.
