Research direction

Start by reviewing the original BPO issue 21331 and reproducing the unicode-escape behavior described in the title on Python 3.4 or a current checkout. Trace the Unicode codec entry points and existing codec tests; done means reversing the encoding preserves the original result and the behavior is covered by a regression test.
