Codecs would hardly ever raises exception here.
Usually, exception raised here would be a MemoryError. The unicode
string we are trying to encode is just decoded by same codec. If codec
raises exception other than MemoryError, the codec will likely have problem.
I attached a script to print exception raised by codec. I wrote a "buggy"
encoder, which never return string but raises an exception.
