Please always provide a minimal testcase, otherwise people have to do a
lot of work simply to get where you are..

  $ cat testcase.py
  # coding=3Dutf-8
  TO_SUPERSCRIPT =3D {
      0x2b: '=E2=81=BA',
      0x2d: '=E2=81=BB',
      0x30: '=E2=81=B0',
      0x31: '=C2=B9',
      0x32: '=C2=B2',
      0x33: '=C2=B3',
      0x34: '=E2=81=B4',
      0x35: '=E2=81=B5',
      0x36: '=E2=81=B6',
      0x37: '=E2=81=B7',
      0x38: '=E2=81=B8',
      0x39: '=E2=81=B9'
      }
  #! Python 2.7+ can use a dictionary comprehension instead:
  FROM_SUPERSCRIPT =3D {
      ord(sup): normal for (normal, sup) in list(TO_SUPERSCRIPT.items())}

  $ python2 testcase.py=20=20
  Traceback (most recent call last):
    File "testcase.py", line 18, in <module>
      ord(sup): normal for (normal, sup) in list(TO_SUPERSCRIPT.items())}
    File "testcase.py", line 18, in <dictcomp>
      ord(sup): normal for (normal, sup) in list(TO_SUPERSCRIPT.items())}
  TypeError: ord() expected a character, but string of length 3 found


Under Python 2.x, list(TO_SUPERSCRIPT.items()) is:

  [(43, '\xe2\x81\xba'),
   (45, '\xe2\x81\xbb'),
   (48, '\xe2\x81\xb0'),
   [=E2=80=A6]
  ]

ie. strings with a length of 3 whilst ord() takes a single char. These
should therefore be probably defined as:

  TO_SUPERSCRIPT =3D {
      0x2b: u'=E2=81=BA',
      0x2d: u'=E2=81=BB',
  [=E2=80=A6]

.. instead, but I haven't tested or confirmed or anythinged that; I'll
leave it with you and upstream.

I also couldn't help notice:
