I don't see any unnecessary overhead and using the wrappers
is really easy, e.g.:

#
# Application uses Latin-1 for I/O, terminal uses UTF-8
#
import codecs, sys

# Make stdout translate Latin-1 output into UTF-8 output
sys.stdout = codecs.EncodedFile(sys.stdout, 'latin-1', 'utf-8')

# Have stdin translate Latin-1 input into UTF-8 input
sys.stdin = codecs.EncodedFile(sys.stdin, 'utf-8', 'latin-1')

We should probably extend the support in StreamRecoder (which
is used by the above EncodedFile helper) to also support Unicode
input to .write() and have a special codec 'unicode' that converts
Unicode to Unicode, so that you can request the EncodedFile object
to return Unicode for .read().
