Looks great... a bit much exposure, maybe ;-)

Note that the stackable stream example will need a small bit
of updating (the return is wrong -- the API was changed since I
programmed the example):

import codecs,sys

# Convert Unicode -> UTF-8
(e,d,sr,sw) = codecs.lookup('utf-8')
unicode_to_utf8 = sw(sys.stdout)

# Convert Latin-1 -> Unicode during .write
(e,d,sr,sw) = codecs.lookup('latin-1')
class StreamRewriter(codecs.StreamWriter):

    encode = e
    decode = d

    def write(self,object):

        """ Writes the object's contents encoded to self.stream
            and returns the number of bytes written.
        """
        data,consumed = self.decode(object,self.errors)
        self.stream.write(data)
    
latin1_to_utf8 = StreamRewriter(unicode_to_utf8)

# Now install
sys.stdout = latin1_to_utf8

# All subsequent prints will output Latin-1 strings using UTF-8
# characters...
print 'Hello World !'
print 'Héllò Wörld !'
print 'ÄÖÜäöüß'
