Unicode Files in 2.6
The preceding discussion applies to Python 3.0’s string types and files. You can achieve similar effects for Unicode files in 2.6, but the interface is different. If you replace str with unicode and open with codecs.open, the result is essentially the same in 2.6:
C:\misc> c:\python26\python
>>> S = u'A\xc4B\xe8C'
>>> print S
AÄBèC
>>> len(S)
5
>>> S.encode('latin-1')
'A\xc4B\xe8C'
>>> S.encode('utf-8')
'A\xc3\x84B\xc3\xa8C'
>>> import codecs
>>> codecs.open('latindata', 'w', encoding='latin-1').write(S)
>>> codecs.open('utfdata', 'w', encoding='utf-8').write(S)
>>> open('latindata', 'rb').read()
'A\xc4B\xe8C'
>>> open('utfdata', 'rb').read()
'A\xc3\x84B\xc3\xa8C'
>>> codecs.open('latindata', 'r', encoding='latin-1').read()
u'A\xc4B\xe8C'
>>> codecs.open('utfdata', 'r', encoding='utf-8').read()
u'A\xc4B\xe8C'
