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