Some thought on Points I found while investigating further.

- A lot of people uses utf-8 for their encoding, such as de_DE.utf8.
  In such case,  backslashescape trick doesn't work.
  I need to find a way to select an appropriate codec to render
  unwanted characters as \uXXXX.

- io.TextIOWrapper doesn't provide interface to change encoding
  and error-handler after it was created. This feature is supported
  in PEP-3116, but isn't impletented at this time. Will it be
  It would be nice if we have optional encoding and errors args for print()
  and TextIOWrapper.write(), so people can write
  print(repr(obj), 'koi8-r', 'backslashescape').
