# Think carefully before adding tests here. In general this should be
# used only for about three categories of tests:
#
# (1) tests that absolutely require 'use utf8', and since that in general
# shouldn't be needed as the utf8 is being obsoleted, this should
# have rather few tests. If you want to test Unicode and regexes,
# you probably want to go to op/regexp or op/pat; if you want to test
# split, go to op/split; pack, op/pack; appending or joining,
# op/append or op/join, and so forth
#
# (2) tests that have to do with Unicode tokenizing (though it's likely
# that all the other Unicode tests sprinkled around the t/**/*.t are
# going to catch that)
#
# (3) complicated tests that simultaneously stress so many Unicode features
# that deciding into which other test script the tests should go to
# is hard -- maybe consider breaking up the complicated test
